    Always unlock pages when returning from writepage
    
    Writepage has a return path which returns an error with a locked
    page. However, all returns that are not AOP_WRITEPAGE_ACTIVATE must
    unlock their pages - using this codepath would leave a stray page lock,
    which would eventually hang the machine.
    
    The logic behind the -EIO return was also incorrect. In the Linux page
    cache model, truncates simply reduce the size recorded in the inode. If
    there are pages pending writeback then they may still have writepage() called
    upon them - it's up to the writepage routine to discard the write
    request (rather than returning an error)
