drm/panfrost: Remove unused variables in panfrost_job_close()

stable inclusion
from stable-5.10.8
commit 27c6968cfb7641c40b5750179f332ed3da930665
bugzilla: 47450

--------------------------------

commit 7d6763ab upstream.

Commit a17d609e ("drm/panfrost: Don't corrupt the queue mutex on
open/close") left unused variables behind, thus generating a warning
at compilation time. Remove those variables.
