nvmet-file: fix nvmet_file_flush() always returning an error
Presently, nvmet_file_flush() always returns a call to
errno_to_nvme_status() but that helper doesn't take into account the
case when errno=0. So nvmet_file_flush() always returns an error code.
All other callers of errno_to_nvme_status() check for success before
calling it.
To fix this, ensure errno_to_nvme_status() returns success if the
errno is zero. This should prevent future mistakes like this from
happening.
Fixes: c6aa3542e010 ("nvmet: add error log support for file backend")
