There are the following problems with lvm completions:
1)_lvm_physicalvolumes() only gets PVs that belong to a VG. In some
  cases like pvremove we can use all PVs including those not included
  in any VGs.
  solution: Add _lvm_physicalvolumes_all to get all PVs and correct
            all the commands.

2)pvcreate should be able to use all block devcices.
  solution: Add _lvm_filedir() to use _filedir except set $cur to /dev
            when $cur is empty.

3)when /etc/lvm/lvm.conf silent is 1 there is no output for vg/lv/pvscan,
  bash-completion will not work.
  solution: Check the value of silent option. If it is 1 then temporarily
            set silent 0 and recover back to 1 after the command executed.
