target-mips: fix compiler warnings (clang 5)

static code analyzer complain:

target/mips/helper.c:453:5: warning: Function call argument is an uninitialized value
qemu_log_mask(CPU_LOG_MMU,
^~~~~~~~~~~~~~~~~~~~~~~~~~

'physical' and 'prot' are uninitialized if 'ret' is not TLBRET_MATCH.

Backports commit def74c0cf05722b2e502d4b4f1219966c5b0cbd3 from qemu
