UBIFS: simplify UBIFS Kconfig menu
Remove debug message level and debug checks Kconfig options as they proved to be useless anyway. We have sysfs interface which we can use for fine-grained debugging messages and checks selection, see Documentation/filesystems/ubifs.txt for mode details.

+ This option enables UBIFS debugging support. It makes sure various
+ assertions, self-checks, debugging messages and test modes are compiled
+ in (this all is compiled out otherwise). Assertions are light-weight
+ and this option also enables them. Self-checks, debugging messages and
+ test modes are switched off by default. Thus, it is safe and actually
+ recommended to have debugging support enabled, and it should not slow
+ down UBIFS. You can then further enable / disable individual debugging
+ features using UBIFS module parameters and the corresponding sysfs
+ interfaces.
