Subject: NFS41: fix error of setting blocklayoutdriver

From: Peng Tao <[email protected]>

commit dc182549d439f60c332bf74d7f220a1bccf37da6 upstream.

After commit e38eb650 (NFS: set_pnfs_layoutdriver() from
nfs4_proc_fsinfo()), set_pnfs_layoutdriver() is called inside
nfs4_proc_fsinfo(), but pnfs_blksize is not set. It causes setting
blocklayoutdriver failure and pnfsblock mount failure.
