Subject: fs/notify/fanotify/fanotify_user.c: fix FAN_MARK_FLUSH flag checking
If fanotify_mark is called with illegal value of arguments flags and marks
it usually returns EINVAL.
When fanotify_mark is called with FAN_MARK_FLUSH the argument flags is not
checked for irrelevant flags like FAN_MARK_IGNORED_MASK.
The patch removes this inconsistency.
If an irrelevant flag is set error EINVAL is returned.
