btrfs: Introduce new mount option usebackuproot to replace recovery
Current "recovery" mount option will only try to use backup root.
However the word "recovery" is too generic and may be confusing for some
users.
Here introduce a new and more specific mount option, "usebackuproot" to
replace "recovery" mount option.
"Recovery" will be kept for compatibility reason, but will be
deprecated.
Also, since "usebackuproot" will only affect mount behavior and after
open_ctree() it has nothing to do with the filesystem, so clear the flag
after mount succeeded.
This provides the basis for later unified "norecovery" mount option.

[ dropped usebackuproot from show_mount, added note about 'recovery' to
docs ]
