    9pfs: convert 'len/copied_len' field in V9fsXattr to the type of uint64_t
    
    The 'len' in V9fsXattr comes from the 'size' argument in setxattr()
    function in guest. The setxattr() function's declaration is this:
    
    int setxattr(const char *path, const char *name,
                 const void *value, size_t size, int flags);
    
    and 'size' is treated as u64 in linux kernel client code:
    
    int p9_client_xattrcreate(struct p9_fid *fid, const char *name,
                              u64 attr_size, int flags)
    
    So the 'len' should have an type of 'uint64_t'.
    The 'copied_len' in V9fsXattr is used to account for copied bytes, it
    should also have an type of 'uint64_t'.
