src/h264.c: drop num_slices field; kernel infers from queued controls

Browse Source 
decode->num_slices was the last field on v4l2_ctrl_h264_decode_params
that didn't survive the upstream cleanup. The kernel now infers the
slice count from how many slice_params controls were queued via the
request API for the given OUTPUT buffer; no explicit count is needed.

This was the only remaining build error; library should now compile clean
against current linux-api-headers.
