[PATCH 10/20] smartpqi: wake up drives after os resumes from suspend

[Don Brace]

From: Dave Carroll <david.carr...@microsemi.com>

- set allow_restart option during scsi_device init.
   This allows the kernel to send a START/STOP Unit command
   to the drive if it encounters a 4/2 check condition in sense data.
