tcg/mips: fix TLB loading for BE host with 32-bit guests
For 32-bit guest, we load a 32-bit address from the TLB, so there is no need to compensate for the low or high part. This fixes 32-bit guests on big-endian hosts. Cc: qemu-stable@nongnu.org Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
