1. Fix reporting GID table addition events.
2. Enable vlan based GID entries only when VLAN is enabled at compile
time (test CONFIG_VLAN_8021Q / CONFIG_VLAN_8021Q_MODULE).

When IPV6 is not enabled:
ERROR: "register_inet6addr_notifier" [drivers/infiniband/hw/ocrdma/ocrdma.ko] undefined!
ERROR: "unregister_inet6addr_notifier" [drivers/infiniband/hw/ocrdma/ocrdma.ko] undefined!
Fix this by wrapping the inet6 calls in #ifdef IPV6. Also make the
ocrdma module depend on (IPV6 || IPV6=n) to forbid the case of modular
ipv6 but built-in ocrdma (which can't work, because ocrdma calls ipv6
functions).

The ocrdma_alloc_lkey() function never returns NULL pointers -- it

Events sent to ocrdma_inet6addr_event() are sent from an atomic context,
therefore we can't try to lock a mutex within the notifier callback.
We could just switch the mutex to a spinlock since all it does it
protect a list, but I've gone ahead and switched the list to use RCU
instead. I couldn't fully test it since I don't have IB hardware, so
if it doesn't fully work for some reason let me know and I'll switch
it back to using a spinlock.

We need to set ib_evt.device, or else ib_dispatch_event() will crash
when we call it for unaffiliated events (and consumers may get
confused in their QP/CQ/SRQ event handler for affiliated events).
Also fix sparse warning:
drivers/infiniband/hw/ocrdma/ocrdma_hw.c:678:36: warning: Using plain integer as NULL pointer
There's no need to clear ib_evt, since every member is initialized.

First, fix
drivers/infiniband/hw/ocrdma/ocrdma_verbs.c: In function 'ocrdma_alloc_pd':
drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:371:17: warning: 'dpp_page_addr' may be used uninitialized in this function [-Wuninitialized]
drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:337:6: note: 'dpp_page_addr' was declared here
which seems that it may border on a bug (the call to ocrdma_del_mmap()
might conceivably do bad things if pd->dpp_enabled is not set and
dpp_page_addr ends up with just the wrong value).
Also take care of:
drivers/infiniband/hw/ocrdma/ocrdma_hw.c: In function 'ocrdma_init_hw':
drivers/infiniband/hw/ocrdma/ocrdma_hw.c:2587:5: warning: 'status' may be used uninitialized in this function [-Wuninitialized]
drivers/infiniband/hw/ocrdma/ocrdma_hw.c:2549:17: note: 'status' was declared here
which is only real if num_eq == 0, which should be impossible.
