Martin KaFai Lau a9482f3b48 bpf: net: Change sk_getsockopt() to take the sockptr_t argument ...

[ Upstream commit 4ff09db1b79b98b4a2a7511571c640b76cab3beb ]

This patch changes sk_getsockopt() to take the sockptr_t argument
such that it can be used by bpf_getsockopt(SOL_SOCKET) in a
latter patch.

security_socket_getpeersec_stream() is not changed.  It stays
with the __user ptr (optval.user and optlen.user) to avoid changes
to other security hooks.  bpf_getsockopt(SOL_SOCKET) also does not
support SO_PEERSEC.
