scsi: lpfc: Fix removal of SCSI transport device get and put on dev structure
The lpfc driver is calling get_device and put_device on scsi_fc_transport
device structure. When this code was removed, the driver triggered an oops
in "scsi_is_host_dev" when the first SCSI target was unregistered from the
transport.
The reason the calls were necessary is that the driver is calling
scsi_remove_host too early, before the target rports are unregistered and
the scsi devices disconnected from the scsi_host. The fc_host was torn
down during fc_remove_host.
Fix by moving the lpfc_pci_remove_one_s3/s4 calls to scsi_remove_host to
after the nodes are cleaned up. Remove the get_device and put_device calls
and the supporting code.
