Tony Hutter 3ee4e6d8b7 vdev_id: Fix partition regular expression
Given a DM device name, the old vdev_id script would extract any text
after a 'p' as the partition number.  It then appends "-part" + the
partition number to the name, giving a by-vdev name like "L0-part5".

This works fine if the DM name is like 'dm-2p5', but doesn't work if
the DM name is a multipath name like "mpatha".  In those cases it
incorrectly matches the 'p' in "mpatha", giving by-vdev names like
"L0-partatha".

This patch fixes the issue by making the partition regex match stricter.
