[ofa-general] [IPoIB][RFC] remove redundant gid query

[James Lentini]

Both ipoib_add_port() and ipoib_mcast_join_task() query the GID at 
index 0 to setup the ipoib_dev_priv structure's local_gid and the 
net_device structure's dev_addr. There does not appear to be a way for 
ipoib_mcast_join_task() to be executed before ipoib_add_port() 
completes. Therefore, the work done in ipoib_mcast_join_task() appears 
to be redundant.
