Peter Hutterer 6b6afd3d01 Xext: return BadAccess if PickPointer fails (#45796) ...

PickPointer or PickKeyboard return NULL, all MDs are currently disabled and
we cannot emulate a core event. This wasn't anticipated by the protocol, so
we don't really have an error code we may use here - BadAccess is simply the
least bad of the possible ones.

And returning BadAccess beats crashing the server.
