[SCSI] mptsas: wide port support

* Wide port support added - using James Bottomley's new SAS wide port API.
(There is a known problem in sas transport layer reported yesterday to
James. The Kobject dev.bus_ids for end devices are not unique across
expanders. I have added a work around in this patch, where I asigning
an unique port identifier for every port within the host - this solves
the problem, but I expect a fix from James in the sas transport).

* Adding target_alloc and target_destroy entry points, and moving code over
from the slave entry points.

* The renaming of some mptscsih_xxx functions declared in mptsas.c,
to mptsas_xxx.

* Target Reset moved from slave_destroy to hotplug work thread
handling (with regard to device removal). Also inhibit IO to end device
while device is being broken down . Talked to James Smart about this
at Linux Expo (with questions of how the fc transport handles this).

* Cleaning up the kzalloc's, and kfree's
