Fix two inconsistencies in handling fixed-function texture coordinate set generation
Prevent off-by-one bug leaving the texture coordinate set 0 always enabled if
it ever was used. This makes the code consistent with its apparent purpose.
When enabling / disabling texture coordinate sets, call glPathTexGen
only if path rendering is applicable. This makes the functions
consistent with GrGpuGL::resetContext.
