How to restore screen when plymouthd crash

[fykcee1 at gmail.com]

Hi all,

It is good if plymouthd restores screen then crash, the steps should
include:
1. Set terminal to text mode.
2. chvt to a proper tty.

The attachment is a patch for example. I'm not sure which tty to chvt when
crash happens, any suggestions?

BTW,
1. What will plymouthd act, if user changes VT while showing splash?
2. I observed ply_terminal_lock/unlock failure -- invalid argument of ioctl,
what does that suggest?

Thanks.
