[PATCH v4 4/9] kasan/xtensa: call kasan_init_generic in kasan_init

[Sabyrzhan Tasbolatov <snovitoll@gmail.com>]

Call kasan_init_generic() which handles Generic KASAN initialization
and prints the banner. Since xtensa doesn't select ARCH_DEFER_KASAN,
kasan_enable() will be a no-op.

Note that arch/xtensa still uses "current" instead of "init_task" pointer
in `current->kasan_depth = 0;` to enable error messages. This is left
unchanged as it cannot be tested.
