Improve 'zpool import' EBUSY error message

When a device is already open O_EXCL by another process the
`zpool import` will correctly fail.  However, the default failure
message isn't very helpful.  It may in fact be harmful if you
take its advise and destroy your pool.

    cannot import 'tank': pool is busy
            Destroy and re-create the pool from
            a backup source.

Improve the error message in the EBUSY case to simply print a
message indicating that the devices are current in use.  The user
will need to manually identify which process has the device open
exclusively and why.
