[SCSI] hpsa: remove scan thread
The intent of the scan thread was to allow a UNIT ATTENTION/LUN DATA CHANGED condition encountered in the interrupt handler to trigger a rescan of devices, which can't be done in interrupt context. However, we weren't able to get this to work, due to multiple such UNIT ATTENTION conditions arriving during the rescan, during updating of the SCSI mid layer, etc. There's no way to tell the devices, "stand still while I scan you!" Since it doesn't work, there's no point in having the thread, as the rescan triggered via ioctl or sysfs can be done without such a thread.
