filter-mpath: remove superfluous error message about mpath major not equal to dm major

This is a regression caused by commit 3bd90488545a4ad5374b4e0f1daba6cf16ae6ae8.
The error message added with that commit "mpath major %d is not dm major %d" is
superfluous.

When scanning for mpath components, we're looking for a parent device.
But this parent device is not necessarily an mpath device (so the dm device)
if it exists - it can be any other device layered on top (e.g. an MD RAID device).
