rS366269: Fallback to software for more GCM and CCM requests.

Summary

ccr(4) uses software to handle GCM and CCM requests not supported by
the crypto engine (e.g. with only AAD and no payload). This change
adds a fallback for a few more requests such as those with more SGL
entries than can fit in a work request (this can happen for GCM when
decrypting a TLS record split across 15 or more packets).
