[ Upstream commit 603c4690b01aaffe3a6c3605a429f6dac39852ae ]

ipv6 bit is wrongly set by the below which causes fatal adapter lookup
engine errors for ipv4 connections while destroying a listener. Fix it to
properly check the local address for ipv6.

Fixes: 3408be145a5d ("RDMA/cxgb4: Fix adapter LE hash errors while destroying ipv6 listening server")
