NFS: Ensure nfs_wcc_update_inode always converts file size to loff_t
The nfs_wcc_update_inode() function omits logic to convert the type of the NFS on-the-wire value of a file's size (__u64) to the type of file size value stored in struct inode (loff_t, which is signed). Everywhere else in the NFS client I checked already correctly converts the file size type. This effects only very large files.
