btrfs-progs: cli-tests: add test case for return value of "btrfs subvlume create"

Browse Source 
The test case would check if "btrfs subvolume create":

- Report error on an existing path
- Still report error if mulitple paths are given and one of them already
  exists
- For above case, still created a subvolume for the good parameter
