[SCSI] fix sign extension with 1.5TB usb-storage LBD=y
Shifting an unsigned char implicitly casts it to a signed int. This
caused 'lba' to sign-extend and Linux would then try READ CAPACITY 16
which was not supported by at least one drive. Using the
get_unaligned_be*() helpers keeps us from having to worry about how the
extension might occur.
