[PATCH] drm/panthor: Fix the panthor_gpu_coherency_init() error path

[Boris Brezillon]

The panthor_gpu_coherency_init() call has been moved around, but the
error path hasn't been adjusted accordingly. Make sure we undo what
has been done before this call in case of failure.

Fixes: 7d5a3b22f5b5 ("drm/panthor: Call panthor_gpu_coherency_init() after PM resume()")
