crypto: testmgr - avoid DMA mapping from text, rodata, stack

Browse source 
With DMA_API_DEBUG set, following warnings are emitted
(tested on CAAM accelerator):
DMA-API: device driver maps memory from kernel text or rodata
DMA-API: device driver maps memory from stack
and the culprits are:
-key in __test_aead and __test_hash
-result in __test_hash

MAX_KEYLEN is changed to accommodate maximum key length from
existing test vectors in crypto/testmgr.h (131 bytes) and rounded.
