Kernel: Use non-locking {Nonnull,}RefPtr for OpenFileDescription
This patch switches away from {Nonnull,}LockRefPtr to the non-locking smart pointers throughout the kernel. I've looked at the handful of places where these were being persisted and I don't see any race situations. Note that the process file descriptor table (Process::m_fds) was already guarded via MutexProtected.
