Arnaud Pouliquen 19882a49b2 remoteproc: stm32_rproc: Add mutex protection for workqueue 
[ Upstream commit 35bdafda40 ]

The workqueue may execute late even after remoteproc is stopped or
stopping, some resources (rpmsg device and endpoint) have been
released in rproc_stop_subdevices(), then rproc_vq_interrupt()
accessing these resources will cause kernel dump.

Call trace:
virtqueue_add_inbuf
virtqueue_add_inbuf
rpmsg_recv_single
rpmsg_recv_done
vring_interrupt
stm32_rproc_mb_vq_work
process_one_work
worker_thread
kthread
