[PATCH] scsi: elx: Fix memory leak on scsi_add_host_with_dma failure

If scsi_add_host_with_dma() fails in efct_scsi_new_device() or
efct_scsi_new_vport(), the Scsi_Host allocated by scsi_host_alloc()
is never released, causing a memory leak.

The caller's error path has no knowledge of this internal allocation:
 - efct_scsi_new_device's caller (efct_xport_initialize) only frees
   the xport structure, not the Scsi_Host.
 - efct_scsi_new_vport's caller chain (efct_vport_create ->
   fc_vport_setup) only cleans up the fc_vport structure itself,
   not the vport's Scsi_Host allocated inside efct_scsi_new_vport.

Add the missing scsi_host_put() calls before each error return.
