hvsi: don't panic on tty_register_driver failure
The alloc_tty_driver failure is handled gracefully in hvsi_init. But
tty_register_driver is not. panic is called if that one fails.
So handle the failure of tty_register_driver gracefully too. This will
keep at least the console functional as it was enabled earlier by
console_initcall in hvsi_console_init. Instead of shooting down the
whole system.
This means, we disable interrupts and restore hvsi_wait back to
poll_for_state().
