[PATCH 2/6] media: staging: rkisp1: params: in stop_streaming, use list_splice_init to move the buffers

[Dafna Hirschfeld <dafna.hirschfeld@xxxxxxxxxxxxx>]

Currently the code uses 'list_cut_position' to move the
buffers to a temporary list. Replace it with
'list_splice_init'. This is nicer since we don't need
to access params.prev. Also, replace INIT_LIST_HEAD
with the simpler LIST_HEAD.
