NFS: Don't overfill uncached readdir pages
[ Upstream commit d9c4e39c ] If we're doing an uncached read of the directory, then we ideally want to read only the exact set of entries that will fit in the buffer supplied by the getdents() system call. So unlike the case where we're reading into the page cache, let's send only one READDIR call, before trying to fill up the buffer.
