nilfs2: fix infinite loop in nilfs_palloc_freev function
After having applied commit 9954e7af14868b8b ("nilfs2: add free entries count only if clear bit operation succeeded"), a free routine of nilfs came to fall into an infinite loop, outputting the same message endlessly: nilfs_palloc_freev: entry number 29497 already freed nilfs_palloc_freev: entry number 29497 already freed nilfs_palloc_freev: entry number 29497 already freed nilfs_palloc_freev: entry number 29497 already freed nilfs_palloc_freev: entry number 29497 already freed ... That patch broke the routine so that a loop counter is never updated in an abnormal state. This fixes the regression. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
