Refine and correct futureTexture setting in GVRMaterial
Refine and correct futureTexture setting in GVRMaterial

GVRMaterial spawns a new thread to set a future texture and the thread is blocked once
the future texture is not finish loading. However, if a texture is already loaded e.g.,
for the preloaded textures, it is not only unnecessary to spawn a new thread, but also
could lead to scheduling issue once the thread pool/system is crowed, such that even a texture
is set to a material, the setting thread is not being executed in the next frame but later.
