possible typo on btree_iter.c @ line 924

[jpsollie]

I noticed the following 2 (very similar) lines:

bch2_bpos_to_text(&PBUF(buf3), b->data->min_key); 
bch2_bpos_to_text(&PBUF(buf3), b->data->max_key);

is it possible the latter one needs to point to buf4? this one was allocated, a few lines above, but never used
