Stale entries in the CQ being destroyed causes hardware to generate
EQEs indefinitely for a given CQ. Thus causing uncontrolled execution
of irq_handler. This patch fixes this using following sementics:
* irq_handler will ring EQ doorbell atleast once and implement budgeting scheme.
* cq_destroy will count number of valid entires during destroy and ring
cq-db so that hardware does not generate uncontrolled EQE.
* cq_destroy will synchronize with last running irq_handler instance.
* arm_cq will always defer arming CQ till poll_cq, except for the first arm_cq call.
* poll_cq will always ring cq-db with arm=SET if arm_cq was called prior to enter poll_cq.
* poll_cq will always ring cq-db with arm=UNSET if arm_cq was not called prior to enter poll_cq.

drivers/infiniband/hw/ocrdma/ocrdma_verbs.c: In function ‘_ocrdma_modify_qp’:
drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:1299:31: error: ‘old_qps’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
status = ocrdma_mbx_modify_qp(dev, qp, attr, attr_mask, old_qps);
ocrdma_mbx_modify_qp() (and subsequent calls) doesn't appear to use old_qps
so it doesn't need to be passed on. Removing the variable results in the
warning going away.

This patch is similar in spirit to the "IB/mlx4: Handle Ethernet L2
parameters for IP based GID addressing". It handles the fact that IP
based RoCE gids don't store Ethernet L2 parameters, MAC and VLAN.
When building an address handle, instead of parsing the dgid to
get the MAC and VLAN, take them from the address handle attributes.

Create_CQ verb doesn't provide a PD pointer. So, until now we are
creating all (both userspace and kernel) CQ DB regions from PD0. This
will result in mmapping PD0 to applications. A rogue userspace
application can mess things up.
Also more serious issues is even the be2net NIC uses PD0.
This patch addresses this problem by:
1) Create a PD page for every userspace application when the
alloc_ucontext is called. This will be destroyed in
dealloc_ucontext.
2) All CQs for that context will use the PD allocated in ucontext.
3) The first create_PD call from application will result in returning
the PD address from its ucontext (no new PD will be created).
4) For subsecquent create_pd calls from application, we create new PDs for
the application.
