ncsid: Fix if_packet warnings
The new Docker CI now hits the following error.
```
/usr/include/linux/if_packet.h:24:17: error: flexible array member 'sockaddr_ll::<unnamed union>::<unnamed struct>::sll_addr_flex' not at end of 'class ncsi::SockIO'
24 | __DECLARE_FLEX_ARRAY(unsigned char, sll_addr_flex);
| ^~~~~~~~~~~~~~~~~~~~
../subprojects/ncsid/src/ncsi_sockio.h:55:15: note: next member 'const int ncsi::SockIO::kpoll_timeout_' declared here
55 | const int kpoll_timeout_ = 10;
| ^~~~~~~~~~~~~~
../subprojects/ncsid/src/ncsi_sockio.h:29:7: note: in the definition of 'class ncsi::SockIO'
29 | class SockIO : public net::SockIO
```
Removed the sockaddr_ll variable.
