The driver creates its own per-CPU threads which are updated based on
CPU hotplug events. It is also possible to use kworkers and remove some
of the kthread infrastrucure.
The code checked ->thread to decide if there is an active per-CPU
thread. By using the kworker infrastructure this is no longer
possible (or required). The thread pointer is saved in `kthread' instead
of `thread' so anything trying to use thread is caught by the
compiler. Currently only the bnx2fc driver is using struct fcoe_percpu_s
and the kthread member.
After a CPU went offline, we may still enqueue items on the "offline"
CPU. This isn't much of a problem. The work will be done on a random
CPU. The allocated crc_eof_page page won't be cleaned up. It is probably
expected that the CPU comes up at some point so it should not be a
problem. The crc_eof_page memory is released of course once the module
is removed.
This patch was only compile-tested due to -ENODEV.

When we are in connection recovery and the internal command timer on a
request pops, either the scsi_cmnd->device or scsi_cmnd->device->host
back pointers may be NULL as the device that the command that the
request was submitted on may have been subsequently reaped due to the
connection recovery. This can cause one or both of the pointers above to
be NULL and cause a system crash if we try to return the command to the
midlayer.
Instead, double check the pointers before the return to the midlayer so
as to prevent the crash and let the upper layers finish the session
recovery and rediscover the device.

Easy enough fix, we can just move the stats collection later in the function
where we are sure we won't preempt or sleep. This also allows us to not have to
enable pre-emption when doing a per-cpu lookup, since we're certain not to get

If bnx2fc_allocate_hash_table() for some reasons fails, it is possible that the
hash_tbl_segments or the hash_tbl_pbl pointers are NULL.
In this case bnx2fc_free_hash_table() will panic the system.
this patch also fixes a memory leak, the hash_tbl_segments pointer was never
freed.
