ref: gl: fix out of bounds access

Browse Source 
On GPUs where GL_ARB_shading_language_100 isn't available (i.e. all mobile GPUs
I believe) this function would return total amount of texture units available.

But ref_gl only tracks and uses MAX_TEXTURE_UNITS texture units, causing memory
corruption in functions that doesn't check the limit.
