scsi: avoid pointless memory allocation in scsi_alloc_target()

As we already know the index of the requested target in
scsi_alloc_target() we can try to fetch it first before trying
to allocate a new one. This will save us a pointless memory
allocation in case the target is already present and uncontended.
