btrfs: fix printing of mount info messages for NODATACOW/NODATASUM

The NODATASUM message was printed twice by mistake and the NODATACOW was
missing from the 'unset' part.  Fix the duplication and make the output
look the same.

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