Johan Almbladh 8110ba0977 bpf: Fix BSWAP 32 and 16 on MIPS64 ...

The 16/32-bit byteswap implementations for MIPS64r1 and earlier do
not have an explicit zero extension afterwards. The input is first
sign-extended to 64 bits, and the byteswap sequence can then leave
the result sign-extended depending on the value of the low bits.

Add the missing zero-extension.

Found with test_bpf on MIPS64r1 emulated by QEMU.
