Annie Li 57a52d7449 x86/microcode/AMD: Do not return error when microcode update is not necessary ...

[ Upstream commit b43dc4ab09 ]

After

  6f059e634dcd("x86/microcode: Clarify the late load logic"),

if the load is up-to-date, the AMD side returns UCODE_OK which leads to
load_late_locked() returning -EBADFD.

Handle UCODE_OK in the switch case to avoid this error.
