Majd Dibbiny 8fe8bacb92 IB/core: Add ordered workqueue for RoCE GID management 
Currently the RoCE GID management uses the ib_wq to do add and delete new GIDs
according to the netdev events.

The ib_wq isn't an ordered workqueue and thus two work elements can be executed
concurrently which will result in unexpected behavior and inconsistency of the
GIDs cache content.

Example:
ifconfig eth1 11.11.11.11/16 up

This command will invoke the following netdev events in the following order:
1. NETDEV_UP
2. NETDEV_DOWN
3. NETDEV_UP

If (2) and (3) will be executed concurrently or in reverse order, instead of
having a new GID with 11.11.11.11 IP, we will end up without any new GIDs.
