Subject: [PATCH 284/284] posix: log aio_error return codes in
posix_fs_health_check
Problem: Sometime brick is going down to health check thread is
failed without logging error codes return by aio system calls.
As per aio_error man page it returns a positive error number
if the asynchronous I/O operation failed.
Solution: log aio_error return codes in error message
