Patch src/amdgpu_glamor.c to remove dead call

xorg/xserver no longer exports glamor_egl_destroy_textured_pixmap,
instead assuming that fbDestroyPixmap will call it, and thus calling it
outside of the xserver codebase is redundant.  Removing the call
prevents a runtime link error when loading amdgpu_drv.so, and doesn't
seem to cause a system (running a modern xorg-server) to catch fire.
