Gorka Eguileor 64cbaaea47 FC: Ignore some HBAs from map for single WWNN
Current FC OS-Brick code only checks for single WWNN to exclude some
HBAs from scanning when we don't receive an initiator_target_map from
the backend.

There are storage arrays,like XtremIO, that due to their architecture
and design have all target ports automatically mapped to LUNs and are
returning the initiator_target_map, but some of those ports may not be
connected to our HBAs, so we end up with another case of bug #1765000.

This patch makes sure that we always check if the target implements
single WWNN, not only when we don't receive the initiator_target_map.

With this we decrease the likelihood of ending with unexpected devices
in our system, because now we will ignore unconnected HBAs (even if
reported in the initiator_target_map) if we are working with single WWNN
target.
