fsnotify: initialize the group->num_marks in a better place
fsnotify: initialize the group->num_marks in a better place

Currently the comments say that group->num_marks is held because the group
is on the fsnotify_group list.  This isn't strictly the case, we really
just hold the num_marks for the life of the group (any time group->refcnt
is != 0)  This patch moves the initialization stuff and makes it clear when
it is really being held.
