MultipathDevice needs its own .updateSysfsPath(), because self.name is
"mpath0" but the sysfs directory is /sys/class/block/dm-0 .
Hopefully dm-${MINOR} is good enough.

Could use
get_sysfs_path_by_name("dm-%d" % (self._pyBlockMultiPath.bdev.minor,))
from storage.miscutils instead. Doesn't really gain much, but we could reduce
the locations where we have "/sys/class/block" coded.
