    vfs_bio: initialize pctries
    
    bufobj_init depends on fields bo_dirty.bv_root and bo_clean.bv_root
    being zeroed on entry and pctrie_init zeroing whatever is passed to
    them, and so does not call pctrie_init for either of them. That fails
    if pctrie_init ever changes to do something other that zeroing data,
    so add explicit calls to them.
