Zhang Shurong fba9c24c19 firmware: meson_sm: fix to avoid potential NULL pointer dereference 
commit f2ed165619 upstream.

of_match_device() may fail and returns a NULL pointer.

Fix this by checking the return value of of_match_device.

Fixes: 8cde3c2153 ("firmware: meson_sm: Rework driver as a proper platform driver")
