media: staging: rkisp1: cap: in stream start, replace calls to rkisp1_handle_buffer...

The function 'rkisp1_stream_start' calls 'rkisp1_handle_buffer'
in order to update the 'buf.curr' and 'buf.next' fields and
configure the device before streaming starts. This cause a wrong
increment of the debugs field 'frame_drop'. This patch replaces
the call to 'rkisp1_handle_buffer' with a call to
'rkisp1_set_next_buf'.
