RDMA/cxgb4: Fix adapter LE hash errors while destroying ipv6 listening server

BugLink: https://bugs.launchpad.net/bugs/1923220
[ Upstream commit 3408be145a5d6418ff955fe5badde652be90e700 ]

Not setting the ipv6 bit while destroying ipv6 listening servers may
result in potential fatal adapter errors due to lookup engine memory hash
errors. Therefore always set ipv6 field while destroying ipv6 listening
servers.
