aacraid: Refactor for sas transport and bug fixes

This patchset primarily lays the foundation for adding sas transport support to the aacraid driver. Being said these patches are mainly code refactors, bug fixes and improvements.

- Fixed a udev inquiry race condition
- Fixed a kdump hang issue which occurs in case of error recovery in kdump
- Made improvements to ioctl reset and reset_host sysfs reset paths
- Changed the code to retrieve lun information into stand alone functions.
- Merged container and hba hotplug event processing (device addition and and removal into single function)
- Removed scsi_scan_host for safw devices and now explicitly add devices retrieved from the fw.
- Reschedule scan in driver fails to retrieve lun information from fw. (usually works in a few attempts)
- Rescan worker waits for any pending EH recovery before rescanning
- Do not trigger rescan worker in kdump kernel
