s3-spoolss: Improve memory efficiency.
p->mem_ctx is a relatively long lived context as it will not be freed until a full request is served. In spoolss we do a lot of operations including opening new pipes to connect to winreg. Use more shortlived temporary contexts to avoid leaking a lot of memory on p->mem_ctx and carrying it around untill all the operations in the current call are done.
