RDMA/erdma: Support create_ah/destroy_ah in non-sleepable contexts
The RDMA CM module might invoke erdma_create_ah() or erdma_destroy_ah()
in a non-sleepable context. Both of these functions will call the
erdma_post_cmd_wait(), which can potentially sleep and occasionally lead
to a hard lockup. Therefore, post the create_ah and destroy_ah commands in
polling mode if the RDMA_CREATE_AH_SLEEPABLE and RDMA_DESTROY_AH_SLEEPABLE
flags are not set, respectively.

RDMA/erdma: Support non-sleeping erdma_post_cmd_wait()
Several scenarios require posting commands to the cmdq in a non-sleepable
context. For example, the cm_alloc_msg() might call erdma_create_ah()
while still holding a spinlock. So we add support for non-sleeping
erdma_post_cmd_wait().

RDMA/erdma: Add the query_qp command to the cmdq
Certian QP attributes, such as sq_draining, can only be obtained
by querying the hardware on the erdma RoCEv2 device. To address this,
we add the query_qp command to the cmdq and parse the response to
retrieve corresponding QP attributes.

The QP state machines in the RoCEv2 and iWARP protocols are

device, we provide the erdma_modify_qp_rocev2() interface,
which transitions the QP state and modifies QP attributes
accordingly.

The erdma_query_pkey() interface queries the PKey at the specified

table can be obtained by calling the erdma_query_port() and
erdma_get_port_immutable() interfaces.
