remoteproc: stm32_rproc: Add mutex protection for workqueue
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:

rpmsg_recv_done
vring_interrupt
