[SCSI] Add target alloc/destroy callbacks to the host template
This gives the HBA driver notice when a target is created and destroyed to allow it to manage its own target based allocations accordingly. This is a much reduced verson of the original patch sent in by James.Smart@Emulex.com Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
