Subject: [PATCH] libmultipath: fix detect alua corner case

If retain_attach_hw_handler = no, then the paths tpgs state will never
be checked, and the multipath device will always select the alua
handler, if no other handler is selected. the paths tpgs state
should be checked, regardless of the retain_hwhandler value.
