[SCSI] make scsi_eh_try_stu use block timeout

scsi_eh_try_stu() was still using the timeout parameter in the device
which is now not set (i.e. zero filled) meaning that it waited no time
at all for the start unit command to complete (leading the routine to
conclude failure every time).  This lead to a 2.6.27 regression:

Where firewire devices that were non spec compliant wouldn't spin up.

Fix this by using the block queue timeout value instead.
