libmultipath: remove _filter_* blacklist functions
The one point of these functions was for _filter_path(), and that wasn't
improved by using them. Since filter_path() only printed one message at
the end, you could have situations where the wwid was blacklisted, but
the blacklist message included the vendor/product instead. Also, the
protocol and property messages were printed twice, and if the device was
on multiple whitelists, only the last one is printed.
