Introduce the function isert_setup_id(). This function creates and sets up
an RDMA CM ID. Move the isert_portal_listen() call into isert_portal_create().

[ bvanassche: edited patch description and dropped support for older kernel
versions in the PRINT_INFO() statement ]

When the low level driver exercises the hot unplug they would call
rdma_cm cma_remove_one which would fire DEVICE_REMOVAL event to all cma
consumers. Now, if consumer doesn't make sure they destroy all IB
objects created on that IB device instance prior to finalizing all
processing of DEVICE_REMOVAL callback, rdma_cm will let the lld to
de-register with IB core and destroy the IB device instance. And if the
consumer calls (say) ib_dereg_mr(), it will crash since that dev object
is NULL.
In the current implementation, iser-target just initiates the cleanup
and returns from DEVICE_REMOVAL callback. This deferred work creates a
race between iser-target cleaning IB objects(say MR) and lld destroying
IB device instance.
This patch includes the following fixes
-> make sure that consumer frees all IB objects associated with device
instance
-> return non-zero from the callback to destroy the rdma_cm id

Move the isert_cm_disconnect_handler() definition, pass the event type to
isert_cm_evt_listener_handler() instead of the struct rdma_cm_event pointer
and change the return value of isert_cm_evt_listener_handler() from 0 /
-EINVAL into -1.

Bart Van Assche noted that currently there are more people using the
32gbit driver than there are people using the older one. So it might
make sense to finally make switch and default to the 32gbit driver.

Although qla-32gbit is mentioned in the README, but there wasn't really a
way to enable it sans editing the code.
This commit adds an ability to enable the driver by passing
`QLA_32GBIT=y` variable at build time.
