crypto: testmgr - don't DMA map IV from stack in test_skcipher()
Fix the "DMA-API: device driver maps memory from stack" warning
generated when crypto accelerators map the IV.
Note: while so far this has been only a warning and thus a theoretical
issue, on latest kernel trees ablkcipher algorithms fail when IV
is on the stack.
Both caam/jr and caam/qi2 fail in the same way, i.e. same incorrect
ciphertexts. Below is log for caam/qi2:
