Vasily Gorbik 92ae0c1efc s390/boot: Respect kaslr_enabled() for identity randomization ...

CONFIG_RANDOMIZE_IDENTITY_BASE only enables support for randomizing the
identity mapping base. The randomization (identity base != 0) itself
should happen only when KASLR is enabled at runtime.

Guard the __identity_base update with kaslr_enabled() so nokaslr (and
other KASLR-disabled cases) keep the non-randomized identity mapping at 0.
