Memory leak in function add_banner

Memory leak in function add_banner.
The memory leak is reported by a static analyzer tool developed at CAST (https://www.linkedin.com/company/cast-center).

Specifically, dynamic memories are allocated here and here if cupsArrayAdd fails to add temp here, allocated memories remain not freed. There are similar cases in other functions which use cupsArrayAdd.

Hmm, this leak is easier to follow than #6145. Anyone from the team seen this? Seems like a memory leak to me.
