scsi: ufs: add instance number to UFS debug-fs entry
UFS exposes a debug-fs directory with various information under
the name "ufs", which will not scale in case more than one UFS
controller is available in the system.
Add the instance number (inherited from the scsi host number) to
the debug-fs entry name.
