Subject: [PATCH 2/2] autofs: use wake_up() instead of wake_up_interruptible(()

In autofs_wait_release() wake_up() is used to wake up processes waiting
on a mount callback to complete which matches the wait_event_killable()
in autofs_wait().

But in autofs_catatonic_mode() the wake_up_interruptible() was not also
changed at the time autofs_wait_release() was changed.
