4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bart Van Assche <bart.vanass...@sandisk.com>
commit 89bfce763e43fa4897e0d3af6b29ed909df64cfd upstream.
activate_path() is renamed to activate_path_work() which now calls
activate_or_offline_path(). activate_or_offline_path() will be used
by the next commit.
