scsi: ibmvfc: Allocate/free queue resource only during probe/remove
Currently, the sub-queues and event pool resources are allocated/freed for
every CRQ connection event such as reset and LPM. This exposes the driver
to a couple issues. First the inefficiency of freeing and reallocating
memory that can simply be resued after being sanitized. Further, a system
under memory pressue runs the risk of allocation failures that could result
in a crippled driver. Finally, there is a race window where command
submission/compeletion can try to pull/return elements from/to an event
pool that is being deleted or already has been deleted due to the lack of
host state around freeing/allocating resources. The following is an example
of list corruption following a live partition migration (LPM):
