ibmvnic: queue reset work in system_long_wq
The reset process for ibmvnic commonly takes multiple seconds, clearly
making it inappropriate for schedule_work/system_wq. The reason to make
this change is that ibmvnic's use of the default system-wide workqueue
for a relatively long-running work item can negatively affect other
workqueue users. So, queue the relatively slow reset job to the
system_long_wq.
