But, in case of mte_enable_kernel_asymm() need return to change kasan_flag_write_only = false when it doesn't support which used in KASAN Kunit test. If we don't return anything, when user set the write_only but HW doesn't support it, KUNIT test get failure since kasan_write_only_enabled() return true thou HW doesn't support it.
