If no system call is actually made because the syscall number (now in orig_eax) is bad, then the %eax value set by ptrace should be returned to the user. But, instead it gets reset to -ENOSYS again. This is a regression from the native 32-bit kernel. This change fixes it by leaving the return value alone after entry tracing.
