Andreas Kling e33dadbdd6 Kernel: Do a bit more of do_exec() before disabling interrupts. ...

We definitely need to replace m_executable before clearing interrupts, since
otherwise we might call ~Custody() which would make it assert in locking.
Also avoid calling FileDescriptor::metadata() repeatedly and just cache the
result from the first call.

I also added a comment at the point where we've decided to commit to the new
executable and follow through with the swap.
