accel/ivpu: Fix deadlock in ivpu_ms_cleanup()
Fix deadlock in ivpu_ms_cleanup() by preventing runtime resume after
file_priv->ms_lock is acquired.
During a failure in runtime resume, a cold boot is executed, which
calls ivpu_ms_cleanup_all(). This function calls ivpu_ms_cleanup()
that acquires file_priv->ms_lock and causes the deadlock.
Fixes: cdfad4db7756 ("accel/ivpu: Add NPU profiling support")
