proc: free kstack buffers when debug permission changesHEADmain

The kern.proc.kstack handler allocates its output and stack buffers
before deliberately checking p_candebug again under the process lock.
If trace-control state changes between authorization checks, the failure
path balances the process and exec state but leaks both buffers.
