xen/netfront: don't bug in case of too many frags
commit ad4f15dc2c70b1de5e0a64d27335962fbc9cf71c upstream.
Commit 57f230ab04d291 ("xen/netfront: raise max number of slots in
xennet_get_responses()") raised the max number of allowed slots by one.
This seems to be problematic in some configurations with netback using
a larger MAX_SKB_FRAGS value (e.g. old Linux kernel with MAX_SKB_FRAGS
defined as 18 instead of nowadays 17).
Instead of BUG_ON() in this case just fall back to retransmission.
Fixes: 57f230ab04d291 ("xen/netfront: raise max number of slots in xennet_get_responses()")
