[PATCH 2/3] btrfs: fix warning messages not printing interval at unpin_extent_range()

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

At unpin_extent_range() we print warning messages that are supposed to
print an interval in the form "[X, Y)", with the first element being an
inclusive start offset and the second element being the exclusive end
offset of a range. However we end up printing the range's length instead
of the range's exclusive end offset, so fix that to avoid having confusing
and non-sense messages in case we hit one of these unexpected scenarios.

Fixes: 00deaf04df35 ("btrfs: log messages at unpin_extent_range() during unexpected cases")
