Exit GLContextEGL Initialization if Config is NULL

We are seeing a group of gpu crashes that occur at engle
glGetConfigAttrib, with SEGV_MAPERR @0x0000006c. 0x6c is the member
offset for egl::Config::renderableType, which means the egl::Config is
NULL. Unclear yet why chrome running on a VM with 0x0 as gpu vendor
does not fallback to software mode earlier and crashed here.

Adding a guard to early out the context initialization here for now, it
should help gpu fallback to software mode.
