filesystem: add back the mountsByPath map
bf17c3e 
Add back the mountsByPath map, which indexes all Mounts by mountpoint.
This is needed again.

To avoid confusion, also rename two local variables named mountsByPath.

mountsByPath won't contain nil entries, so also make AllFilesystems()
use it instead of mountsByDevice.  This shouldn't change its behavior.
