perf/breakpoint: Pass new breakpoint type to modify_breakpoint_slot()
We soon won't be able to rely on bp->attr anymore to get the new
type of the modifying breakpoint because the new attributes are going
to be copied only once we successfully modified the breakpoint slot.
This will fix the current misdesigned layout where the new attr are
copied to the modifying breakpoint before we actually know if the
modification will be validated.
In order to prepare for that, allow modify_breakpoint_slot() to take
the new breakpoint type.
