crypto: qce driver fixes for gcm

I've sent the v2 patches I had generated before I had run checkpatch.pl. Sorry about the noise.

One comment about the splitting string across lines: It's the parameter description string, and the split is between the description and the explanation about the values. I hope this is OK, if not I'll send a v4.

v2->v3
Corrected style issues pointed out by checkpatch.pl

v1->v2
Add a parameter to set the fallback threshold.
Fix for xts-aes-qce hanging when (len % 512 != 0)

Eneas U de Queiroz (3):
crypto: qce - use cryptlen when adding extra sgl
crypto: qce - use AES fallback for small requests
crypto: qce - handle AES-XTS cases that qce fails
