server: fix memory leak on writes
...
This was unnoticed for a long time because it simply did not occur
in ordinary MARS Light workloads.

aio: fix portability to changed kernels / kthread implementation
...
In the long term, mars_aio will be replaced anyway because it
uses userspace concepts like ioctx.
Don't use the internal kthread_stop_nowait() anymore.
It is too cumbersome to catch up with upstream development.

The error code -EIO should always refer to a problem of
lower storage laysers. Thus MARS should not generate that
code itself, but other ones.

On slow networks, the generic net_io_timeout is too long if you are
impatiently waiting for disconnect.
Change the io_timeout of the individual client brick to a short value.
