With this change, a single call to TEE_AEEncryptFinal() checks both
the output data buffer size and the tag buffer size and return
TEE_ERROR_SHORT_BUFFER with both expected size if at least one
of the provided buffer is too short.
Before this change caller may need to call twice TEE_AEEncryptFinal()
in the right order to get the output buffers sizes, first for the
output data size then for the tag data size.
