qcacmn: Record few more ce desc event during post_recv_buffers

Browse Source 
CE events are not recorded during nbuf allocation and
nbuf map done in hif_post_recv_buffers_for_pipe.

Add few more events to be recorded to know the exact
time when nbuf allocation and map is done with respect
to rx_desc_completion and rx_post_desc events.
