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.
