[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.
