Chenx Dust 526dcbe120 xwayland: fix segment fault in xwl_glamor_gbm_init_main_dev
Function `xwl_glamor_gbm_init_main_dev` does not check whether
`xwl_screen->default_feedback.main_dev` a.k.a. `main_dev` is a
valid pointer. This result in some special situation where main
linux-dmabuf device is not accessible, such as KWin nested desktop,
raising segment fault.

This commit add a null pointer check to prevent crashing.
