cxgbe(4): Save proper zone index on low memory in refill_fl().
When refill_fl() fails to allocate large (9/16KB) mbuf cluster, it
falls back to safe (4KB) ones. But it still saved into sd->zidx
the original fl->zidx instead of fl->safe_zidx. It caused problems
with the later use of that cluster, including memory and/or data
corruption.
While there, make refill_fl() to use the safe zone for all following
clusters for the call, since it is unlikely that large succeed.
