[PATCH NFS 1/3] Lose second parameter of nfs_block_size().

[PATCH NFS 1/3] Lose second parameter of nfs_block_size().

Most calls to nfs_block_size() were done with a NULL pointer as second
parameter anyway.  We can simply calculate the number of bits ourselves
instead of using that ugly pointer thingy.
