Abusing ability of major UAs cover minor ones we may not account UAs for inactive ports. Allocate UAs storage for port and start accounting only after some initiator from that port fetched its first POWER ON OCCURRED. This reduces per-LUN CTL memory usage from >1MB to less then 100K. MFC after: 1 month
