  [X86] Fix assertion when lowering FP_ROUND (#185562)

443ce5569ee9854cfef1139cf6b9cf05165e0902 caused us to start hitting
assertions with non-standard vector widths (<3 x float>) in this case
now that node types are actually enforced. There was a place in
X86ISelLowering.cpp where we just passed along a 64-bit integer whereas
other places constructing a CVTPS2PH node specifically construct a new
integer.
