9p: use kvzalloc for readdir buffer
The readdir buffer is sized to msize, so kzalloc() can fail under
fragmentation with a page allocation failure in v9fs_alloc_rdir_buf()
/ v9fs_dir_readdir_dotl().
The buffer is only a response sink and is never pack_sg_list()'d,
so kvzalloc() is safe for all transports, unlike the fcall buffers
fixed in e21d451a82f3 ("9p: Use kvmalloc for message buffers on
supported transports").
