qcacld-3.0: compile ol rx thread code only for legacy targets

Currently ol rx thread code is under QCA_CONFIG_SMP macro, which is
enabled for all the targets. But LI, BE and RH family targets don't
use this ol rx thread implementation. Hence, compile out ol rx thread
code for LI, BE and RH targets.
