[PATCH] NFS2: Calculate 'w' a bit later in nfsaclsvc_encode_getaclres() 

NFS2: Calculate 'w' a bit later in nfsaclsvc_encode_getaclres()
      This is a small performance optimization since we can return before
      needing 'w'. It also saves a few bytes of .text :
      Before:
           text    data     bss     dec     hex filename
           2406     212       0    2618     a3a fs/nfsd/nfs2acl.o
      After:
           text    data     bss     dec     hex filename
           2400     212       0    2612     a34 fs/nfsd/nfs2acl.o
