media: staging: rkisp1: params: in the isr, return if buffer list is empty

Currently the code in the isr checks if the buffer list is not
empty before referencing a buffer and then check again if the
buffer is not NULL. Instead we can save one 'if' statement by
returning if the buffers list is empty.
Also remove non-helpful inline doc 'get one empty buffer'
