Remove checkCipherData

[Al1c3-1337]

Remove checkCipherData, as it causes problems with CA_ECDH_AES_CBC_CMAC_192 and CA_ECDH_AES_CBC_CMAC_256. Block size is not always a multiple of key size (ex AES). E.g. using CA_ECDH_AES_CBC_CMAC_192 the encoded key has a length of 192 bits (24 bytes), of which the AES block size (128 bits / 16 bytes) is not a multiple. An incorrect block size is also detected by the underlying classes. Removing this function call made it possible to run conformance tests with CA_ECDH_AES_CBC_CMAC_192 and CA_ECDH_AES_CBC_CMAC_256.

I attached a debugging screenshot of the updateEncryptedIV function showing the exception from the mentioned function. Version 2.2.7 was used for confirming the bug.
