[SCSI] scsi_debug: prepare to enable clustering
Currently, clustering support for scsi_debug is disabled. This is
because there are for_each_sg() loops which assume that each sg list
element is consisted with a single page. But enabling clustering
support, each sg list element for scsi commands can be consisted with
multiple pages.
This replaces these for_each_sg() loops with sg mapping iterator which
is capable of handling each sg list element is consisted with multiple
pages.
