NFS: Fix the initialisation of the readdir 'cookieverf' array
When the NFS_COOKIEVERF helper macro was converted into a static inline function in commit 99fadcd764 (nfs: convert NFS_*(inode) helpers to static inline), we broke the initialisation of the readdir cookies, since that depended on doing a memset with an argument of 'sizeof(NFS_COOKIEVERF(inode))' which therefore changed from sizeof(be32 cookieverf[2]) to sizeof(be32 *). At this point, NFS_COOKIEVERF seems to be more of an obfuscation than a helper, so the best thing would be to just get rid of it.
