scsi: scsi_debug: Add new error injection type: Abort Failed
Add error injection type 3 to make scsi_debug_abort() return FAILED. Fail
abort command format:
+--------+------+-------------------------------------------------------+
| Column | Type | Description |
+--------+------+-------------------------------------------------------+
| 1 | u8 | Error type, fixed to 0x3 |
+--------+------+-------------------------------------------------------+
| 2 | s32 | Error count |
| | | 0: this rule will be ignored |
| | | positive: the rule will always take effect |
| | | negative: the rule takes effect n times where -n is |
| | | the value given. Ignored after n times |
+--------+------+-------------------------------------------------------+
| 3 | x8 | SCSI command opcode, 0xff for all commands |
