x86/power/32: Move SYSENTER MSR restoration to fix_processor_context()
x86_64 restores system call MSRs in fix_processor_context(), and
x86_32 restored them along with segment registers. The 64-bit
variant makes more sense, so move the 32-bit code to match the
64-bit code.
No side effects are expected to runtime behavior.
