uas: Fix memory management
The scsi-host structure is refcounted, scsi_remove_host tears down the scsi-host but does not decrement the refcount, so we need to call scsi_put_host on disconnect to get the underlying memory to be freed. After calling scsi_remove_host, the scsi-core may still hold a reference to the scsi-host, iow we may still get called after uas_disconnect, but we do our own life cycle management of uas_devinfo, freeing it on disconnect, and thus may end up using devinfo after it has been freed. Switch to letting scsi_host_alloc allocate and manage the memory for us. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>
