av1_cx_iface.c: move #if outside of macro

This fixes the build under Visual Studio using cl.exe after:
  0bfd0b97dc Fix a bug when CONFIG_REALTIME_ONLY=1

av1\av1_cx_iface.c(3069,1): warning C4002: too many argumengs for
  function-like macro invocation 'AOMMIN'
av1\av1_cx_iface.c(3060,28): error C2121: '#': invalid character:
  possibly the result of a macro expansion
av1\av1_cx_iface.c(3060,28): error C2059: syntax error: 'if'
