egl/dri2/x11: Don't clobber _EGLDriver::API

dri2_initialize_x11_swrast() does a strange thing. For some extensions
it doesn't support, it sets the corresponding functions in
_EGLDriver::API to NULL. The intention here is clear, but misplaced.

NULL or not, the function pointers never get called because their
extensions aren't supported.
