Allow to run skcipher speed for given algorithm.
Case 600 is modified to cover ENCRYPT and DECRYPT
directions.
Example:
modprobe tcrypt mode=600 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)

- modifying case 600, instead of using separate cases for
