drivers: modem: wncm14a2a: remove left-over includes

Commit fd14014 ("net/tcp: Move net_tcp_set_hdr() away from net
core") removed <net/tcp.h>.  This results in a not found error being
generated when CONFIG_NET_TCP is enabled.

We also, don't need to include <net/udp.h> anymore due to new
net_pkt API changes.

Let's clean up the includes by removing both of them.
