[multipathd] remove the retry login in uev_remove_path()

The last uev_remove_path() should succeed since in addition to
removing from the map the path being removed by the uevent, it will
also remove all paths found in the current map which do not appear
in pathvec.

This avoids long delays due to path verifying in the old code.
