[PATCH v2] crypto: tcrypt - add skcipher speed for given alg

[PATCH v2] crypto: tcrypt - add skcipher speed for given alg

[Sergey Portnoy]

Allow to run skcipher speed for given algorithm.
Two separate cases are added to cover ENCRYPT and DECRYPT
directions.

Example:
   modprobe tcrypt mode=611 alg="qat_aes_xts" klen=32

If succeed, the performance numbers will be printed in dmesg:
   testing speed of multibuffer qat_aes_xts (qat_aes_xts) encryption
   test 0 (256 bit key, 16 byte blocks): 1 operation in 14596 cycles (16 bytes)
   ...
   test 6 (256 bit key, 4096 byte blocks): 1 operation in 8053 cycles (4096 bytes)

v1 -> v2

- speed_template is moved to be on-stack and type was corrected to u8
