Btrfs-progs: introduces '-a' option into subvolume list command
We list the subvolumes under current directory according to the input
subvolume.
However, if we still want to list all the subvolumes in the tree, we
can use '-a' option to help us.
There may be two kinds of path: absolute path , relative path .
The absolute path is beginning with "<FS_TREE>"
The relative path is under current path that you input.
