netfilter: nft_bitwise: correct uapi header comment.
The comment documenting how bitwise expressions work includes a table
which summarizes the mask and xor arguments combined to express the
supported boolean operations. However, the row for OR:
mask xor
0 x
is incorrect.
dreg = (sreg & 0) ^ x
is not equivalent to:
dreg = sreg | x
What the code actually does is:
dreg = (sreg & ~x) ^ x
Update the documentation to match.
