[Intel-gfx] [PATCH 8/8] xfree86: Also handle EAGAIN errors from drmSetInterfaceVersion().

[Bryce Harrington]

It has been suggested that the kernel may pass EAGAIN when the device is
unavailable.  This hasn't been seen in practice, and examination of the
function definition in libdrm suggests EAGAIN is handled internally so
would not be seen by the xserver when making this call.  So, this patch
is probably unneeded.  But include support anyway.
