nilfs2: fix imperfect completion wait in nilfs_wait_on_logs

nilfs_wait_on_logs has a potential to slip out before completion of
all bio requests when it met an error.  This synchronization fault may
cause unexpected results, for instance, violative access to freed
segment buffers from an end-bio callback routine.

This fixes the issue by ensuring that nilfs_wait_on_logs waits all
given logs.
