    If a syscall requires a module to be autoloaded, the initial invocation
    of that syscall will return ERESTART.  For amd64's netbsd32_syscall()
    that means we need to back up the PC saved in the trap frame so we can
    re-issue the syscall instruction.  For "normal" syscall traps, we saved
    the instruction length in the trap frame, but this was missing for the
    oosyscall/lcall path.  Since the PC was not backed up, the kernel-only
    value ERESTART was returned to userland, causing all sort of grief for
    old compat_netbsd32 executables!
