dpaa2-eth: use the S/G table cache also for the normal S/G path
Instead of allocating memory for an S/G table each time a nonlinear skb
is processed, and then freeing it on the Tx confirmation path, use the
S/G table cache in order to reuse the memory.
For this to work we have to change the size of the cached buffers so
that it can hold the maximum number of scatterlist entries.
Other than that, each allocate/free call is replaced by a call to the
dpaa2_eth_sgt_get/dpaa2_eth_sgt_recycle functions, introduced in the
previous patch.
