egl: return corresponding offset of EGLImage instead of 0.
The offset should not always be 0. For example, if EGLImage is
created from a 2D texture with EGL_GL_TEXTURE_LEVEL=1, then the
offset should be the actual start of miplevel 1 in bo.
v2: Add version check of __DRIimageExtension implementation
(Suggested by Axel Davy).
v3: Don't add version check of __DRIimageExtension implementation.
Set the offset only when queryImage() succeeds. (Suggested by Emil
Velikov)
