What makes you think this message needs correcting? The code seems to
be checking whether we're freeing an already free bnode, meaning the
message looks correct as is and the proposed change makes it incorrect.

This is wrong. The intended meaning here is "trying to free bnode
which is already free". Please don't send patches for code you don't
understand.

Perhaps inserting an "a" in the message would make it clearer?
(pr_crit("trying to free a free bnode ")
