[PATCH] fix for sd removal loop

Attached is a trivial fix for an excessive loop that is encountered in
removal of the sd module. This case is hit when sd is insmod'ed and rmmod'ed
without any scsi devices being registered. In this case, within exit_sd(), 
sd_template.dev_max remains at zero and the N_USED_SD_MAJORS macro yields an 
incorrect result since it is treating dev_max as an signed number.
