btrfs: fix incorrect log message for nobarrier mount option

commit edf842abe4368ce3c423343cf4b23b210fcf1622 upstream.

Fix a wrong log message that appears when the "nobarrier" mount option
is unset.  When "nobarrier" is unset, barrier is actually enabled.
However, the log incorrectly stated "turning off barriers".

Fixes: eddb1a433f26 ("btrfs: add reconfigure callback for fs_context")
