x86/MCE/AMD: Fix inverted interrupt enablement during storm handling

Browse source

mce_amd_handle_storm() currently does the opposite of what storm
handling needs: it enables thresholding interrupts when a storm is
detected and disables them when the storm subsides.

Flip the "on" function argument before passing it to threshold_restart_bank()
as it should have been done.

To clarify: "on" to mce_handle_storm() means, the storm is on now when
"on" is true, and off when "on" is false.

  [ bp: Simplify. ]
