Fixing that allows to stop messing with ->valid before the driver registration, which is a Good Thing(tm) - we shouldn't have it set before we really have the things set up and ready for line_open(). We need tty_driver available to call tty_{un,}register_device(), so we just stash a reference to it into struct line_driver.

The latter, unfortunately, is incorrect - the first opener might not be through yet. We need to have exclusion covering the entire line_init(), including the blocking parts. Moreover, the next patch will need to widen the exclusion on mconsole side of things, also including the blocking bits, so let's just convert that sucker to mutex...
