net: replace calls to sock->ops->connect() with kernel_connect()
commit 0bdf399342c5 ("net: Avoid address overwrite in kernel_connect")
ensured that kernel_connect() will not overwrite the address parameter
in cases where BPF connect hooks perform an address rewrite. This change
replaces direct calls to sock->ops->connect() in net with kernel_connect()
to make these call safe.
