Andreas Kling 164c9617c3 Kernel: Only lock file descriptor table once in sys$pipe() 
Instead of locking it twice, we now frontload all the work that doesn't
touch the fd table, and then only lock it towards the end of the
syscall.

The benefit here is simplicity. The downside is that we do a bit of
unnecessary work in the EMFILE error case, but we don't need to optimize
that case anyway.
