egl: drop unreachable BAD_NATIVE_WINDOW conditions

The code in _eglCreateWindowSurfaceCommon() already has a NULL check
which handles the condition. There's no point in checking again further
down the stack.

v2: Split the WINDOW vs PIXMAP into separate patches
v3: Resolve typos, s/EGL_PIXMAP_BIT_BIT/EGL_PIXMAP_BIT/
