dm: dump.c: Fix segfault when entry->of_match is NULL

Currently, dm drivers command produces a segfault:
=> dm drivers
Driver                Compatible
--------------------------------
Segmentation fault (core dumped)

This is caused by a NULL pointer dereference of entry->of_match.
Add a check to prevent this.
