Fix code_helper unused argument warning for fr30

fr30 is the only target defining GO_IF_LEGITIMATE_ADDRESS right now, in
which case the `code_helper ch` argument to memory_address_addr_space_p()
is unused and emits a new warning.

gcc/ChangeLog:
	* recog.cc (memory_address_addr_space_p): Mark possibly unused
	argument as unused.
