fsnotify: drop two useless bools in the fnsotify main loop

Browse Source 
The fsnotify main loop has 2 bools which indicated if we processed the
inode or vfsmount mark in that particular pass through the loop.  These
bool can we replaced with the inode_group and vfsmount_group variables
and actually make the code a little easier to understand.
