nilfs2: set bio unplug flag for the last bio in segment
This sets BIO_RW_UNPLUG flag on the last bio of each segment during write. The last bio should be unplugged immediately because the caller waits for the completion after the submission. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
