freedreno/ir3/ra: fix half-class conflicts

On a6xx, half-regs conflict with full-regs.  But we were only setting up
conflicts for the first class (ie. scalar, but not hvec2/hvec3/hvec4),
resulting in higher half-reg classes getting assigned to regs that
overwrite full-regs.

Noticed while trying to enable indirect-sampler (sam.s2en) which uses an
hvec2 argument to pass the sampler/tex index.
