[PATCH] NFS: split nfsi->flags into two fields
Certain bits in nfsi->flags can be manipulated with atomic bitops, and some
are better manipulated via logical bitmask operations.
This patch splits the flags field into two. The next patch introduces atomic
bitops for one of the fields.
Test plan:
Millions of fsx ops on SMP clients.
