[PATCH 4/4] fsnotify: clear marks to 0 in fsnotify_init_mark

[Eric Paris]

Currently fsnotify_init_mark sets some fields to 0/NULL.  Some users
already used some sorts of zalloc, some didn't.  This patch uses memset to
explicitly zero everything in the fsnotify_mark when it is initialized so we
don't have to be careful if fields are later added to marks.
