Subject: [PATCH v9 01/12] kthread: Rename probe_kthread_data() to kthread_probe_data()

A good practice is to prefix the names of functions by the name
of the subsystem.

This patch fixes the name of probe_kthread_data(). The other wrong
functions names are part of the kthread worker API and will be
fixed separately.
