hw-breakpoints: Accept breakpoints on NULL address
Before we had a generic breakpoint API, ptrace was accepting
breakpoints on NULL address in x86. The new API refuse them,
without given strong reasons. We need to follow the previous
behaviour as some userspace apps like Wine need such NULL
breakpoints to ensure old emulated software protections
are still working.
This fixes a 2.6.32 - 2.6.33-x ptrace regression.
