[PATCH btrfs-progs] Documentation: btrfs-man5: Remove nonexistent nousebackuproot option

[Marcos Paulo de Souza]

From: Marcos Paulo de Souza <mpdesouza@suse.com>

Since it's inclusion in b3751c131 ("btrfs-progs: docs: update
btrfs-man5"), this option was never available in kernel, we can only
enable this option using usebackuproot.

Shouldn't this option be plumbed through instead?

As this option is only used at mount time, I don't see why we should be
able to disable using remount for example. Am I missing something?

Thanks,

The default is to not use backup roots, so there's no point in having it
as an explicit option.

Added to devel, thanks.
