context_tracking: Fix noinstr vs KASAN
Low level noinstr context-tracking code is calling out to instrumented
code on KASAN:
vmlinux.o: warning: objtool: __ct_user_enter+0x72: call to __kasan_check_write() leaves .noinstr.text section
vmlinux.o: warning: objtool: __ct_user_exit+0x47: call to __kasan_check_write() leaves .noinstr.text section
Use even lower level atomic methods to avoid the instrumentation.
