MIPS: fw: Allow firmware to pass a empty env
commit ee1809ed7bc456a72dc8410b475b73021a3a68d5 upstream.
fw_getenv will use env entry to determine style of env,
however it is legal for firmware to just pass a empty list.
Check if first entry exist before running strchr to avoid
null pointer dereference.
