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 controls the amount of debugging messages produced by UBIFS.
If reporting bugs, please try to have available a full dump of the
messages at level 1 while the misbehaviour was occurring. Level 2
may become necessary if level 1 messages were not enough to find the
bug. Generally Level 3 should be avoided.
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.
