Lizhi Hou 431e5af9e4 accel/amdxdna: Fix deadlock between context destroy and job timeout

[ Upstream commit ca25834123 ]

Hardware context destroy function holds dev_lock while waiting for all jobs
to complete. The timeout job also needs to acquire dev_lock, this leads to
a deadlock.

Fix the issue by temporarily releasing dev_lock before waiting for all
jobs to finish, and reacquiring it afterward.
