ac/nir: do not reserve user SGPRs for unused descriptor sets

In theory this might lead to corruption if we bind a descriptor
set which is unused, because LLVM is smart and it can re-use
unused user SGPRs. In practice, this doesn't seem to fix
anything.

As a side effect, this will reduce the number of emitted
SH_REG packets.
