  SVN rev 210512 on 2010-07-26 18:54:56Z by jhb
  
  MFC 209948:
  A previous change moved the GETATTR RPC for open() calls that hit in the
  name cache up into nfs_lookup() instead of nfs_open().  Continue this
  trend by flushing the attribute cache for leaf nodes in nfs_lookup() during
  an open() if we do a LOOKUP RPC.  For NFSv3 this should generally be a NOP
  as the attributes are flushed before fetching the post-op attributes from
  the LOOKUP RPC which most (all?) NFSv3 servers provide, so the post-op
  attributes should populate the cache.
  
  Now all NFS open() calls will always clear the cached attributes during the
  nfs_lookup() prior to nfs_open() in the !NMODIFIED case to provide CTOC.
  As a result, we can remove the conditional flushing of the attribute
  cache from nfs_open().
