Subject: [PATCH 2/3] Remove check for a 32-bit cookie in nfsd4_readdir()

Fan Yong <yong.fan@...mcloud.com>  noticed simply setting
O_64BITHASH wouldn't work with nfsd v4, as
nfsd4_readdir() checks for a 32 bit cookie. However, according to RFC 3530
cookies have a 64 bit type and it is also defined as u64
'struct nfsd4_readdir'.
So remove the test for >32-bit values.
