Reported by Clang [-Wunused-but-set-variable]
'commit 480cb846c27b ("block: convert to advancing variants of iov_iter_get_pages{,_alloc}()")' This commit converted iov_iter_advance() to iov_iter_revert(), and not uses variable 'added' anymore but forgot to delete it.
Since 'added' is useless now, remove it for code cleaning.
