drm: Only use DRM_IOCTL_UPDATE_DRAW compat wrapper for compat X86.
Only X86 32-bit uses a different alignment for "unsigned long long" than it's 64-bit counterpart. Therefore this compat translation is only correct, and only needed, when either CONFIG_X86 or CONFIG_IA64. Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Dave Airlie <airlied@redhat.com>
