    x86/xstate: undo bogus adjustment to xsave()
    
    This reverts an unintended change in commit 879b44b041 ("x86/fpu: add
    a per-domain field to set the width of FIP/FDP"), which I had done
    intermediately while fixing the build issue: After having reverted that
    adjustment I must have forgotten to "git add" the adjustment.
