Brian Behlendorf a1eaf0dde0 Exclude log device ashift from normal class
When opening a log device during import its allocation bias will
not yet have been set by vdev_load().  This results in the log
device's ashift being incorrectly applied to the maximum ashift
of the vdevs in the normal class.  Which in turn prevents the
removal of any top-level devices due to the ashift check in the
spa_vdev_remove_top_check() function.

This issue is resolved by including vdev_islog in the check since
it will be set correctly during vdev_open().
