Get rid of the obnoxious backwards tests and it probably fits in 80 columns.

if (!qhandle || !desc || !desc->cb_elems || !desc->desc) {
...

OTOH if it isn't expected that any of these might be NULL just delete
the test.
If they ever are 'accidentally' NULL it is usually easier to debug
the NULL pointer dereference than an obscure error return.
