Subject: [PATCH 3/3] lib: cleanup dead code from lib/percpu_test.c

lib/percpu_test.c code allows to compile either as a loadable modules or
builtin into the kernel.

Current code returns -EAGAIN on successful termination from module_init.
Such a fail will directly unload the module and hence there is no scope
to execute percpu_test_exit on module_exit.
