Blackfin: kgdb_test: rework code to avoid -O0 usage
__kfree_rcu() in rcupdate.h bugs when parameter offset is not a constant at compile time. Since we build the kgdb_test module with -O0 and it includes this header file, we hit the bug. So drop the -O0 and mark the one func we need for the test as noinline (so we can set a breakpoint on it and have it be hit).
