Since commit 1cf4f629d9d2 ("cpu/hotplug: Move online calls to
hotplugged cpu") it is ensured that callbacks of CPU_ONLINE and
CPU_DOWN_PREPARE are processed on the hotplugged cpu. Due to this SMP
function calls are no longer required.

Replace smp_call_function_single() with a direct call of
hw_breakpoint_reset(). To keep the calling convention, interrupts are
explicitely disabled around the call.

While you are at it, could you please also fix a similar instance
in arch/arm64/kernel/debug-monitors.c: hw_breakpoint_reset_notify() ?

Thanks
