nilfs2: cleanup nilfs_clear_inode
This will remove the following unnecessary locks and cleanup code in nilfs_clear_inode(): - unnecessary protection using nilfs_transaction_begin() and nilfs_transaction_end(). - cleanup code of i_dirty list field which is never chained when this function is called. - spinlock used when releasing i_bh field.
