gallium needs to know if the kernel is new enough to support explicit
fencing, dynamically grown ringbuffers, etc.

With a new enough drm/msm, we can let the kernel know about buffers that
are in the bo cache, so the kernel can free them under memory pressure.

It should be a less common case, but it is possible for a single bo to
be on multiple rings, for example when sharing a buffer across multiple
pipe_context's created from same pipe_screen.
So rather than completely fall over in this case, fallback to slow-path
of looping over all bo's in the ring's bo-table (but retain the fast-
path of constant-lookup for the first ring the buffer is on).

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).
v3: Fix kgsl_pipe.c, suggested by Thierry.

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.
