Fix up over-eager 'wait_queue_t' renaming
Commit ac6424b981bc ("sched/wait: Rename wait_queue_t =>
wait_queue_entry_t") had scripted the renaming incorrectly, and didn't
actually check that the 'wait_queue_t' was a full token.
As a result, it also triggered on 'wait_queue_token', and renamed that
to 'wait_queue_entry_token' entry in the autofs4 packet structure
definition too. That was entirely incorrect, and not intended.
The end result built fine when building just the kernel - because
everything had been renamed consistently there - but caused problems in
user space because the "struct autofs_packet_missing" type is exported
as part of the uapi.
This scripts it all back again:
git grep -lw wait_queue_entry_token |
xargs sed -i 's/wait_queue_entry_token/wait_queue_token/g'
and checks the end result.
