Suren Baghdasaryan c944bf60c1 lib/alloc_tag: do not register sysctl interface when CONFIG_SYSCTL=n
Memory allocation profiling is trying to register sysctl interface even
when CONFIG_SYSCTL=n, resulting in proc_do_static_key() being undefined. 
Prevent that by skipping sysctl registration for such configurations.
