Subject: dpaa2-eth: fix draining of S/G cache
Git-commit: 0fe665d42fd0844dbfb60f15b09d71fd0c409b00
Patch-mainline: v5.9-rc1
References: jsc#SLE-12251
On link down, the draining of the S/G cache should be done on all
_possible_ CPUs not just the ones that are online in that moment.
Fix this by changing the iterator.
