Minutes after committing c5b49fe5c62a7f062fd4d19c157e481fc514f584 I
realized 'sda' would also filter out the partition 'sdap4' on the disk
'sdap', not desirable.

This patch essentialy reverts c5b49fe5c62a7f062fd4d19c157e481fc514f584. It
goes through all partitions of a mpath member at the moment we check it's
ignored and adds the partitions explicitly to the filter list.
