eap: Silence uninitialized var warning

Browse Source 
src/eap.c: In function 'eap_rx_packet':
src/eap.c:419:50: error: 'vendor_type' may be used uninitialized in this function [-Werror=maybe-uninitialized]
  419 |  (type == EAP_TYPE_EXPANDED && vendor_id == (id) && vendor_type == (t))
      |                                                  ^~
src/eap.c:430:11: note: 'vendor_type' was declared here
  430 |  uint32_t vendor_type;

It isn't clear why GCC complains about vendor_type, but not vendor_id.
But in all cases if type == EAP_TYPE_EXPANDED, then vendor_type and
vendor_id are set.  Silence this spurious warning.
