scsi: storvsc: Resolve data race in storvsc_probe()
vmscsi_size_delta can be written concurrently by multiple instances of
storvsc_probe(), corresponding to multiple synthetic IDE/SCSI devices;
cf. storvsc_drv's probe_type == PROBE_PREFER_ASYNCHRONOUS. Change the
global variable vmscsi_size_delta to per-synthetic-IDE/SCSI-device.
