egl: fix _eglQuerySurface in EGL_BUFFER_AGE_EXT case
Specification states that in case of error, value should not be
written, patch changes buffer age queries to return -1 in case of
error so that we can skip changing the value.
In addition, small change to droid_query_buffer_age to return 0
in case buffer does not have a back buffer available.
Fixes:
dEQP-EGL.functional.negative_partial_update.not_postable_surface
