sdk_dpaa: ls1043a errata: memory related fixes

Avoid a crash by verifying the allocation return status.

Use the standard API for determining the page order needed for
allocating Jumbo sized skbs.

Explicitly remove the old skb outside the w/a, for both successful and
unsuccessful realignments. Make sure the old skb's memory isn't leaked.
