quota: Propagate error from ->acquire_dquot()
Currently when some error happened in ->acquire_dquot(), dqget() just returned NULL. That was indistinguishable from a case when e.g. someone run quotaoff and so was generally silently ignored. However ->acquire_dquot() can fail because of ENOSPC or EIO in which case user should better know. So propagate error up from ->acquire_dquot properly. Signed-off-by: Jan Kara <jack@suse.cz>
