Subject: drm/panfrost: Fix runtime PM imbalance on error
Git-commit: 64092598c4566dc80a71ca57396dc36fdbf3da4b
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
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.
