fastboot: make scsi probes asynchronous
This patch makes part of the scsi probe (which is mostly device spin up and the partition scan) asynchronous. Only the part that runs after getting the device number allocated is asynchronous, ensuring that device numbering remains stable. Signed-off-by: Arjan van de Ven <arjan@linux.intel.com>
