Add roc_nix_rq_multi_ena_dis() to batch RQ enable/disable mailbox
AQ operations and process them in a single mbox_process() call.
Skip mbox_process() when no messages were queued (e.g. all qid are
UINT16_MAX) by checking num_msgs and msg_size via mbox_nonempty_nolock().

Why can't this be an inline function? large macros are a bad idea.
