nfs: fix anonymous member initializer build failure with older compilers

Browse Source 
Older versions of gcc don't understand named initializers inside a
anonymous structure or union member.  It can be worked around by adding
the bracin gin the initializer for the anonymous member.

Without this, gcc 4.4.4 will fail the build with

    CC      fs/nfs/nfs4state.o
  fs/nfs/nfs4state.c:69: error: unknown field ‘data’ specified in initializer
  fs/nfs/nfs4state.c:69: warning: missing braces around initializer
  fs/nfs/nfs4state.c:69: warning: (near initialization for ‘zero_stateid.<anonymous>.data’)
  make[2]: *** [fs/nfs/nfs4state.o] Error 1
