Subject: ir-keytable: avoid double lock
From: Dan Carpenter <error27@xxxxxxxxx>
It's possible that we wanted to resize to a smaller size but we didn't
have enough memory to create the new table. We need to test for that here
so we don't try to lock twice and dead lock. Also we free the "oldkeymap"
on that path and that would be bad.
