job: Fix missing locking due to mismerge

Browse Source 
job_completed() had a problem with double locking that was recently
fixed independently by two different commits:

"job: Fix nested aio_poll() hanging in job_txn_apply"
"jobs: add exit shim"

One fix removed the first aio_context_acquire(), the other fix removed
the other one. Now we have a bug again and the code is run without any
locking.

Add it back in one of the places.
