btrfs: remove no longer used counter when reading data page
commit ad3fc7946b1829213bbdbb2b9ad0d124b31ae4a7 upstream.
After commit 92082d40976ed0 ("btrfs: integrate page status update for
data read path into begin/end_page_read"), the 'nr' counter at
btrfs_do_readpage() is no longer used, we increment it but we never
read from it. So just remove it.
