  [AMDGPU] Remove unnecessary and broken sign/zero extension in fastdiv (#210348)

Remove unnecessary and broken sign/zero-extension when using float-point
reciprocal to implement division/remainder. This change is analogous to
the change done in https://github.com/llvm/llvm-project/pull/203436 but
in AMDGPUISelLowering.cpp.
