egl: check for NULL value like eglGetSyncAttribKHR does

Browse source 
Commit d1e1563bb6 added a NULL check for eglGetSyncAttribKHR
but eglGetSyncAttrib does not do this. Patch adds same check to
happen with eglGetSyncAttrib.

Fixes crashes in (when exposing EGL 1.5):
   dEQP-EGL.functional.fence_sync.invalid.get_invalid_value
