scsi: core: Use eh_timeout for START STOP UNIT

In some scenarios START STOP UNIT may time out. The default recovery
time of 30 seconds is relatively large. Modifying rq_timeout to adjust
the START STOP UNIT timeout value will affect the regular I/O.

Commit 9728c0814ecb ("[SCSI] make scsi_eh_try_stu use block timeout")
switched to rq_timeout for the START STOP UNIT command. However commit
0816c9251a71 ("[SCSI] Allow error handling timeout to be specified")
introduced an explicit eh_timeout parameter. It makes more sense to
use this value as the timeout for START STOP UNIT.
