[PATCH v2 3/3] asm-generic: remove extra type checking in acquire/release for non-SMP case

[Baokun Li <libaokun1@huawei.com>]

If CONFIG_SMP is not enabled, the smp_load_acquire/smp_store_release is
implemented as READ_ONCE/READ_ONCE and barrier() and type checking.
READ_ONCE/READ_ONCE already checks the pointer type, and then checks it
more stringently outside, but the non-SMP case simply isn't relevant, so
remove the extra compiletime_assert_atomic_type() to avoid compilation
errors.
