Fix multipath bug in vdev_id caused by inconsistent field numbering
The bug is caused by multipath output like this: 35000c50056bd77a7 dm-15 HP,MB3000FCWDH size=2.7T features='0' hwhandler='0' wp=rw |-+- policy='round-robin 0' prio=0 status=active | `- 2:0:16:0 sdq 65:0 active undef running `-+- policy='round-robin 0' prio=0 status=enabled `- 4:0:52:0 sdfp 130:176 active undef running Note that the pipe symbols mean that the field numbering is different between the sdq and sdfp lines. The fix edits out the pipe symbols. Signed-off-by: Ned Bass <bass6@llnl.gov> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #1692
