[PATCH net v2] net/socket: remove unused do_sock_{set,get}sockopt() exports

do_sock_setsockopt() and do_sock_getsockopt() have been exported since
they were split out of the syscall handlers for io_uring to reuse.

io_uring is the only caller outside net/socket.c, and it is never
modular: cmd_net.o is built under obj-$(CONFIG_NET), and both CONFIG_NET
and CONFIG_IO_URING are bool. The declarations in <net/sock.h> are all
it needs, so no module has ever been able to use these exports.

Drop the symbol exports.

Fixes: 0b05b0cd78c9 ("net/socket: Break down __sys_getsockopt")
