  MFC ffs_alloc.c 1.135 - clear i_flag field in recycled inodes

    Log:
    Initialize the inode i_flag field in ffs_valloc() to clean up any
    stale flag bits left over from before the inode was recycled.
  
    Without this change, a leftover IN_SPACECOUNTED flag could prevent
    softdep_freefile() and softdep_releasefile() from incrementing
    fs_pendinginodes.  Because handle_workitem_freefile() unconditionally
    decrements fs_pendinginodes, a negative value could be reported at
    file system unmount time with a message like:
            unmount pending error: blocks 0 files -3
    The pending block count in fs_pendingblocks could also be negative
    for similar reasons.  These errors can cause the data returned by
    statfs() to be slightly incorrect.  Some other cleanup code in
    softdep_releasefile() could also be incorrectly bypassed.
