hw-breakpoints: Check the breakpoint params from perf tools
Perf tools create perf events as disabled in the beginning.
Breakpoints are then considered like ptrace temporary
breakpoints, only meant to reserve a breakpoint slot until we
get all the necessary informations from the user.
In this case, we don't check the address that is breakpointed as
it is NULL in the ptrace case.
But perf tools don't have the same purpose, events are created
disabled to wait for all events to be created before enabling
all of them. We want to check the breakpoint parameters in this
case.
