The test (in the standalone/scrub suite) verifies that the scrubber
detects (and issues a cluster-log error) whenever a mapping entry
("SNA_") is missing in the SnapMapper DB.
Specifically, here the entry is corrupted - shortened as per
https://tracker.ceph.com/issues/56147.

Whenever the scrubber access the SnapMapper for the snaps of a specific
clone, the mapper will now verify that the snaps have the required
mapping DB entries (the 'SNA_' keys).

Due to maintaining super block and other tracking information in the
disk, the entire disk size is not available, so rename the function
to represent that it actually returns available size on the device.
get_available_size() represents together free and used space available
on the device.

In BlockSegmentManager, super block is updated with device size.
But a small amount of device capacity is reserved to store the
super block information and other tracking information.
Number of segments is calculated after discounting super block
size and tracking information size. This creates a mismatch
with the actual available size versus actual number of segments.
Update the available size after considering the reserved device
capacity and the number of segments and segment size.

In reset_device(), if the total number of 512B sectors on the device
is more than INT_MAX then there was a overflow happening, rendering
the nr_sectors as 0, which was causing the failure of the ioctl and
subsequent crash, fix the overflow.

ZNS SSDs have an attribute called zone_capacity which can be less than or
equal to zone_size. zone_capacity represents the actual writable media in
a zone. When zone_capacity is less than zone_size, writing to offsets
beyond zone_capacity will cause write errors.
Set the segment size as equal to zone_capacity, so that segment managers
writes only upto capacity of the zone/segment.
Update device size to actual available bytes so that the gc can kick in
at appropriate thresholds.

For a ZNS device, a open/full zone has to be reset before it can be
reused to write from start. Seastore releases a segment/zone and marks
it empty and expects to be able to write to it from start. So as a part
of release reset the zone, so it moves to empty state on the device.
