scsi: ses: Fix devices attaching to different hosts

On a multipath SAS system some devices don't end up with correct symlinks
from the SCSI device to its enclosure. Some devices even have enclosure
links pointing to enclosures attached to different SCSI hosts.

ses_match_to_enclosure() calls enclosure_for_each_device() which iterates
over all enclosures on the system, not just enclosures attached to the
current SCSI host.

Replace the iteration with a direct call to ses_enclosure_find_by_addr().
