mpt2sas : Rescan topology from Interrupt context instead of work queue

Following host reset its possible that the controller firmware could assign new handles for devices, as well as adding or deleting devices. There is code in the driver that will rescan the topology folowing host reset; updating device handles, and remove devices that are no longer responding. This patch will improve the responsivness by moving this rescaning from the delayed hotplug worker thread to immediately following the host reset.

author and whose hands these patches have been through. If Eric wrote them, and you're just submitting them, I need a From: field at the beginning to change the git authorship (and also the order of signoff needs reversing).

I worked the fix back in May. Kashyap is generating the patch's, and I'm reviewing them.
