evas gl - avoid a possible crash of tex upload of invalid sized image 

so i had a crash where my bt said the image size is 1x1 but the img
struct said its 0x0, so put in protection to not upload a texture from
a 0x0 image... just for now... because this is odd - the image data is
a real ptr i can access and there should be at least 1 pixel... but i
can't be sure this fixes it as this is one of those "one offs" i cant
reproduce...

@fix
