[PATCH 09/13] staging: unisys: visornic: don't destroy global workqueues until devs destroyed

[Benjamin Romer]

From: Tim Sell <Timothy.Sell at unisys.com>

visornic_cleanup() was previously incorrectly destroying its global
workqueues prior to cleaning up the devices which used them.  This patch
corrects the order of these operations.
