scsi: core: Only put parent device if host state differs from SHOST_CREATED 

commit 1e0d4e6225996f05271de1ebcb1a7c9381af0b27 upstream.

get_device(shost->shost_gendev.parent) is called after host state has
switched to SHOST_RUNNING. scsi_host_dev_release() shouldn't release the
parent device if host state is still SHOST_CREATED.
