WARN_ON_SMP(): Allow use in if() statements on UP
Both WARN_ON() and WARN_ON_SMP() should be able to be used in
an if statement.
if (WARN_ON_SMP(foo)) { ... }
Because WARN_ON_SMP() is defined as a do { } while (0) on UP,
it can not be used this way.
Convert it to the same form that WARN_ON() is, even when
CONFIG_SMP is off.
