[SCSI] scsi_debug: fix duplicate dif_errors increment

Browse source 
It is unnecessary to increase dif_errors in dif_verify(), because the
caller will increment it when dif_verify() detects failure.

This bug was introduced by commit beb40ea42b ("[SCSI] scsi_debug:
reduce duplication between prot_verify_read and prot_verify_write")
