MBO: Fix possible NULL pointer dereference on candidate handling

If the driver provides input on MBO transition candidate handling, the
target value in get_mbo_transition_candidate() can be NULL if the driver
provided BSSID is not found in the wpa_supplicant BSS table. And later
it would be dereferenced. Fix this by adding an explicit check before
dereferencing the pointer.
