[ Upstream commit c15e7c62fe ]
If ksmbd_override_fsids() fails, we jump to err_out2. At that point, fp is
NULL because it hasn't been assigned dh_info.fp yet, so ksmbd_fd_put(work,
fp) will not be called. However, dh_info.fp was already inserted into the
session file table by ksmbd_reopen_durable_fd(), so it will leak in the
session file table until the session is closed.
Move fp = dh_info.fp; ahead of the ksmbd_override_fsids() check to fix the
problem.
