netfilter: nfnetlink_cthelper: Remove 'const' and '&' to avoid warnings
The related code can be simplified, and also can avoid related warnings
(with allmodconfig under parisc):
CC [M] net/netfilter/nfnetlink_cthelper.o
net/netfilter/nfnetlink_cthelper.c: In function ‘nfnl_cthelper_from_nlattr’:
net/netfilter/nfnetlink_cthelper.c:97:9: warning: passing argument 1 o ‘memcpy’ discards ‘const’ qualifier from pointer target type [-Wdiscarded-array-qualifiers]
memcpy(&help->data, nla_data(attr), help->helper->data_len);
