target-mips: fix corner case in TLBWR causing QEMU to hang
cpu_mips_get_random() function is used to generate a random index from
CP0.Wired to TLBSize-1 range. Current implementation avoids generating
the same as before value, hence the while loop. If the guest sets
CP0.Wired to TLBSize-1 (which actually does not sound to be very
practical) QEMU will get stuck in the loop infinitely as we always
generate the same index.
