help message of btrfsctl does not tell anything about deletion of a subvolume

[Andreas Philipp]

Hi,

The help message of the btrfsctl command does not tell anything about
the deletion of a subvolume. See patch below.

Kind regards,
Andreas

We have a new command "btrfs subvolume delete <path>" which can be
shortened even as far as "btrfs s d <path>".

Are we going to keep the btrfsctl program indefinitely when we have a
replacement in the "btrfs" program?
