accel/ivpu: Fix PM related deadlocks in MS IOCTLs
Prevent runtime resume/suspend while MS IOCTLs are in progress.
Failed suspend will call ivpu_ms_cleanup() that would try to acquire
file_priv->ms_lock, which is already held by the IOCTLs.
Fixes: cdfad4db7756 ("accel/ivpu: Add NPU profiling support")
