AMDGPU: Fix splitting SMRD with large offset
The splitting of > 4 dword SMRD instructions
if using an offset in an SGPR instead of an immediate
was not setting the destination register,
resulting an an instruction missing an operand
which would assert later.
Test will be included in a following commit
which fixes a related issue.
