RISC-V: Fix bug of TARGET_COMPUTE_MULTILIB implemented in riscv.

MAX_MATCH_SCORE is not assigned anywhere except initialized to 0,
causing BEST_MATCH_MULTI_LIB to always be 0 or -1, which will
cause the result of TARGET_COMPUTE_MULTILIB hook to fail.

gcc/ChangeLog:

	* common/config/riscv/riscv-common.cc (riscv_compute_multilib):
	Fix finding best match score.
