x86/entry: Rename idtentry_enter/exit_cond_rcu() to idtentry_enter/exit()

They were originally called _cond_rcu because they were special
versions with conditional RCU handling.  Now they're the standard
entry and exit path, so the _cond_rcu part is just confusing.  Drop
it.

Also change the signature to make them more extensible and more
foolproof.

This patch makes no functional change -- it's pure refactoring.
