Even though commit df4ec5c3186e796624e4bbf2dc4a269faf2823f6 commented
out most of smartcard code which triggered this error, it still might
happen if a new message is added with an array member.

The reason is a missing declaration of mem_size, which is fixed simply
by checking if the attribute 'nocopy' is present.

The error log follows:

generated_server_demarshallers.c: In function ‘parse_msgc_smartcard_reader_add’:
generated_server_demarshallers.c:1985:30: error: ‘mem_size’ undeclared (first 
use in this function); did you mean ‘nw_size’?
     data = (uint8_t *)malloc(mem_size);
                              ^~~~~~~~
                              nw_size
