SH4: Fix swap.b

The SH4 manual documents the swap.b instruction as follows:

        SWAP.B Rm,Rn
                Rm → swap lower 2 bytes → Rn

Current QEMU code, in addition to the above, also clears the high
16 bits. The immediate breakage I saw is that htonl function applied
to  netmask of 255.255.255.0 gives 0, which breaks all networking.
