Subject: [PATCH] cifs: some missing initializations on replay

In several places in the code, we have a label to signify
the start of the code where a request can be replayed if
necessary. However, some of these places were missing the
necessary reinitializations of certain local variables
before replay.

This change makes sure that these variables get initialized
after the label.
