btrfs-progs: separate command and implementation of chunk-recover code

Browse source 
The command has been moved and we should rename the files accordingly,
so the entry point is now in cmds-rescue.c and the core functionality
in it's own file.

Return codes of btrfs_recover_chunk_tree have been simplified not to
require a define and another file for defintion.
