The z_thread_mark_switched_in() and z_thread_mark_switched_out()
functions make use of k_current_get(). When CONFIG_THREAD_LOCAL_STORAGE
is set, k_current_get() retrieves the current thread pointer from the
TLS area. However, during early boot, those tracing functions get involved
although the TLS area has not yet been initialized.
