[PATCH v2] fstests: common/btrfs: use complete sub command

[Anand Jain]

Search for 'subvolume' in the file common/btrfs failed to find all of
them, leading to a wrong inference for a moment.

Make sure we use the full subcommand name in the btrfs command.

Hum, in my tests realted to subvol delete by id[1], this function
successfully got the subvolid for subvol names like subvol[123].. Do
you have a case where it fails?

Here you meant I reviewed the first version of the patch?
