Allow repair_qgroups() to do silent repair, so it can acts as offline
qgroup rescan.
This provides the basis for later mkfs quota support.

The original qgroup-verify integrates qgroup classification into
report_qgroups(). This behavior makes silent qgroup repair (or offline
rescan) impossible.
To repair qgroup, we must call report_qgroups() to trigger bad qgroup
classification, which will output error message.
This patch moves bad qgroup classification from report_qgroups() to
qgroup_verify_all(). Now report_qgroups() is pretty lightweight, only
doing basic qgroup difference report thus change it type to void.
And since the functionality of qgroup_verify_all() changes, change
callers to handle the new return value correctly.

In fact qgroup-verify is just kind of offline qgroup rescan, and later
mkfs qgroup support will reuse it.
So qgroup-verify doesn't really need to rely the global variable @repair
to check if it should repair qgroups.
Instead check fs_info->readonly to do the repair.

Current kernel only supports qgroup version 1. Make qgroup-verify to
follow this standard.

Commit 078e9a1cc9 ("btrfs-progs: check: enhanced progress indicator")
introduced @qgroup_item_count for progress indicator.
However since we will later introduce silent qgroup rescan
functionality, the @qgroup_item_count pointer can be NULL.
So check if @qgroup_item_count is NULL before accessing it.

Since 1d5b2ad9 ("btrfs-progs: qgroup-verify: Don't treat qgroup
difference as error if the fs hasn't initialized a rescan") a new
message is being printed when the qgroups is incosistent and the rescan
hasn't being executed, so remove the later message send to stderr.
While in this function, simplify the check for a not executed rescan
since !counts.rescan_running and counts.rescan_running == 0 means the
same thing.
