There's a hotplug problem in the way libsas allocates ports: it loops over the available ports first trying to add to an existing for a wide port and otherwise allocating the next free port. This scheme only works if the port array is packed from zero, which fails if a port gets hot unplugged and the array becomes sparse. In that case, a new port is formed even if there's a wide port it should be part of. Fix this by creating two loops over all the ports: the first to see if the phy should be part of a wide port and the second to form a new port in an empty port slot.
