[nf PATCH] netfilter: nft_tproxy: Fix port selector on Big Endian

[Phil Sutter <phil@xxxxxx>]

On Big Endian architectures, u16 port value was extracted from the wrong
parts of u32 sreg_port, just like commit 10596608c4d62 ("netfilter:
nf_tables: fix mismatch in big-endian system") describes.

Fixes: 4ed8eb6570a49 ("netfilter: nf_tables: Add native tproxy support")
