Abeit quite unlikely to get hit by this bug here, let just fix it.

v2: Correct conditional (do not call ioctl(DRM_IOCTL_PRIME_HANDLE_TO_FD)
when we already have the fd).

They are less and easier to track than the public ones. The macro
drm_public will be going away by the end of the series.

Need to update timestamp on all ring's associated with a submit (ie.
both the binning pass and main ring).  Also, make sure nr_reloc's
in particular gets cleared if the rb is reset.

Allow IB to different ringbuffer in addition to just different part of
same ringbuffer.  In particular, we need to add bo's to the parent (ie.
one passed to flush) bo table, since the bo table applies to all the
cmd buffers in submit ioctl.
