UBIFS: remove Kconfig debugging option
Have the debugging stuff always compiled-in instead. It simplifies maintanance a lot. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

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