reiserfs: Fix softlockup while waiting on an inode
When we wait for an inode through reiserfs_iget(), we hold the reiserfs lock. And waiting for an inode may imply waiting for its writeback. But the inode writeback path may also require the reiserfs lock, which leads to a deadlock. We just need to release the reiserfs lock from reiserfs_iget() to fix this.
