Oleg Nesterov f7da04c9e3 ptrace/x86: flush_ptrace_hw_breakpoint() shoule clear the virtual debug registers ...

flush_ptrace_hw_breakpoint() destroys the counters set by ptrace, but
"leaks" ->debugreg6 and ->ptrace_dr7.

The problem is minor, but still it doesn't look right and flush_thread()
did this until commit 66cb591729 ("hw-breakpoints: use the new wrapper
routines to access debug registers in process/thread code").  Now that
PTRACE_DETACH does flush_ too this makes even more sense.
