    xfs: fix for hang during synchronous buffer write error
    
    If removed storage while synchronous buffer write underway,
    "xfslogd" hangs.

    "xfs: fix error handling for synchronous writes"
    
    Given that xfs_bwrite actually does the shutdown already after
    waiting for the b_iodone completion and given that we actually
    found that calling xfs_force_shutdown from inside
    xfs_buf_iodone_callbacks was a major contributor the problem
    it better to drop this call.
