net: fib_rules: Correctly set table field when table number exceeds 8 bits
[ Upstream commit 540e585a79e9d643ede077b73bcc7aa2d7b4d919 ]
In 709772e6e06564ed94ba740de70185ac3d792773, RT_TABLE_COMPAT was added to
allow legacy software to deal with routing table numbers >= 256, but the
same change to FIB rule queries was overlooked.
