meta: Don't modify GL_GENERATE_MIPMAP state when it doesn't exist
This is a bit of a hack. _mesa_meta_GenerateMipmap shouldn't even be
used in contexts where GL_GENERATE_MIPMAP doesn't exist (i.e., core
profile and ES2) because it uses fixed-function, and fixed-function
doesn't exist there either!
A GLSL-based _mesa_meta_GenerateMipmap should be available soon. When
that is available, this patch will be irrelevant and should be reverted.
v2: Change (ctx->API != API_OPENGLES2 && ctx->API != API_OPENGL_CORE) to
(ctx->API == API_OPENGL || ctx->API == API_OPENGLES) based on review
comment from Brian Paul.
