scsi: sd: Use separate buf for START_STOP in sd_spinup_disk()

Browse source

We currently reuse the cmd buffer for the TUR and START_STOP commands
which requires us to reset the buffer when retrying. This has us use
separate buffers for the 2 commands so we can make them const and I think
it makes it easier to handle for retries but does not add too much extra to
the stack use.
