Kernel/VFS: Remove the find_mount_for_guest method

Browse source 
We don't really need this method anymore, because we could just try to
find the mount entry based on the given mount point host custody.

This also allows us to remove the is_vfs_root and root_inode_id methods
from the VirtualFileSystem class.
