Frederic Weisbecker 267a6af608 rcu/exp: Handle RCU expedited grace period kworker allocation failure ...

[ Upstream commit e7539ffc9a770f36bacedcf0fbfb4bf2f244f4a5 ]

Just like is done for the kworker performing nodes initialization,
gracefully handle the possible allocation failure of the RCU expedited
grace period main kworker.

While at it perform a rename of the related checking functions to better
reflect the expedited specifics.
