Subject: [PATCH v1] crypto/qat: make the session struct variable in size
This patch changes the qat firmware session data structure from a fixed size to a variable size which is dependent on the size of the chosen algorithm.
This reduces the amount of bytes which are transferred across PCIe and thus helps to increase qat performance when the accelerator is bound by PCIe.

v1:
* Fixed a compile issue with icc.
