inotify: add do_inotify_init() helper; remove in-kernel call to syscall
Using the inotify-internal do_inotify_init() helper allows us to get rid of the in-kernel call to sys_inotify_init1() syscall. This patch is part of a series which removes in-kernel calls to syscalls. On this basis, the syscall entry path can be streamlined.
