The caller expects panfrost_job_hw_submit() to increase
runtime PM usage counter. The refcount decrement on the
error branch of WARN_ON() will break the counter balance
and needs to be removed.

Changelog:
v2: - Remove refcount decrement on the error path of
WARN_ON() rather than add refcount decrement
on the error path of pm_runtime_get_sync().
