qcacmn: Fix -Wmissing-prototypes in ce_service_srng.c

We want to enable the compiler's -Wmissing-prototypes switch, but
there is existing code in ce_service_srng.c that is generating
warnings.  Fix these warnings by making the following functions
static:
	ce_send_nolock_srng
	ce_sendlist_send_srng
	ce_recv_buf_enqueue_srng
	ce_recv_entries_done_nolock_srng
	ce_send_entries_done_nolock_srng
	ce_completed_recv_next_nolock_srng
	ce_revoke_recv_next_srng
	ce_completed_send_next_nolock_srng
	ce_cancel_send_next_srng
	ce_check_int_watermark_srng
	ce_get_desc_size_srng
	ce_srng_src_ring_setup
	ce_srng_dest_ring_setup
	ce_srng_status_ring_setup
	ce_ring_setup_srng
