[dm-devel] [PATCH] multipath: display average priority as group priority



Display avg priority as group priority

Now average priority is used as path group priority, instead of sum of
priorities of the paths. But while displaying group priority, sum is
being displayed. Change it to print the average priority.

When there are no enabled paths, print 0 as priority.
