ASoC: Intel: atom: Take the drv->lock mutex before calling sst_send_slot_map()

Browse Source 
[ Upstream commit 81630dc042af998b9f58cd8e2c29dab9777ea176 ]

sst_send_slot_map() uses sst_fill_and_send_cmd_unlocked() because in some
places it is called with the drv->lock mutex already held.

So it must always be called with the mutex locked. This commit adds missing
locking in the sst_set_be_modules() code-path.
