nilfs2: fix missing cleanup on rollforward recovery error

In an error injection test of a routine for mount-time recovery, KASAN found a use-after-free bug.

It turned out that if data recovery was performed using partial logs created by dsync writes, but an error occurred before starting the log writer to create a recovered checkpoint, the inodes whose data had been recovered were left in the ns_dirty_files list of the nilfs object and were not freed.

Fix this issue by cleaning up inodes that have read the recovery data if the recovery routine fails midway before the log writer starts.
