Fredrik Strupe f90e3019dd Use PSA_ERROR_INVALID_ARGUMENT for invalid cipher input sizes
... as opposed to PSA_ERROR_BAD_STATE.

The spec on psa_cipher_finish() states that PSA_ERROR_INVALID_ARGUMENT
should be returned when:

"The total input size passed to this operation is not valid for this
particular algorithm. For example, the algorithm is a based on block
cipher and requires a whole number of blocks, but the total input size
is not a multiple of the block size."

Currently, there is a distinction between encryption and decryption
on whether INVALID_ARGUMENT or BAD_STATE is returned, but this is not
a part of the spec.

This fix ensures that PSA_ERROR_INVALID_ARGUMENT is returned
consistently on invalid cipher input sizes.
