[PATCH 06/17] NFS: remove unused page and page2 in nfs4_replace_transport()

[Mike Rapoport (Microsoft)]

Temporary buffers page and page2 allocated by nfs4_replace_transport() and
passed to nfs4_try_replacing_one_location() are never used.

Remove them and the code that allocates and frees memory for these buffers.
