[Devel] [PATCH][INET]: Fix accidentally broken inet(6)_hash_connect's port offset calculations.

The port offset calculations depend on the protocol family, but,
as Adrian noticed, I broke this logic with the commit
5ee31fc1ecdcbc234c8c56dcacef87c8e09909d8
[INET]: Consolidate inet(6)_hash_connect.
Return this logic back, by passing the port offset directly into
the consolidated function.
