x86_64: Zero extend all registers after ptrace in 32bit entry path.
Strictly it's only needed for eax.
It actually does a little more than strictly needed -- the other registers
are already zero extended.
Also remove the now unnecessary and non functional compat task check
in ptrace.
This is CVE-2007-4573
