net: mvpp2: Don't re-use loop iterator

Browse Source 
[ Upstream commit 0aa3ca956c46d849775eae1816cef8fe4bc8b50e ]

This function has a nested loop.  The problem is that both the inside
and outside loop use the same variable as an iterator.  I found this
via static analysis so I'm not sure the impact.  It could be that it
loops forever or, more likely, the loop exits early.
