ubifs: Rework ubifs_assert()
With having access to struct ubifs_info in ubifs_assert() we can
give more information when an assert is failing.
By using ubifs_err() we can tell which UBIFS instance failed.
Also multiple actions can be taken now.
We support:
- report: This is what UBIFS did so far, just report the failure and go
on.
- read-only: Switch to read-only mode.
- panic: shoot the kernel in the head.
