mesa/texture: Also check for LA texture when querying intensity component
size
Gallium may pick L16A16_FLOAT to represent GL_INTENSITY16F if no intensity
format is provided by the driver. However, when calling
glGetTexLevelParameteriv(..., GL_TEXTURE_INTENSITY_SIZE, ...)
mesa will return a zero size because the actually used format has no
intensity channel and as a fallback only the sizes of the red/green
channels are checked.
Also checking for LA sizes in the allocated texture resolves this problem.
v2: Only check alpha channel size and return it (Marek)
L and A size are always the same in this case.
Fixes (on virgl):
ext_framebuffer_multisample-fast-clear GL_ARB_texture_float *
