  AMDGPU: Fix verifier error with argument passed in CSR SGPR

We need to avoid setting the kill flag on the CSR spill if there's an
additional use of the register after the spill.

This does rely on consistency between the entry block liveins and the
MRI's function live ins, which is not something the verifier checks
now.
