gen_tcp:connect/2 crashes with {inet_backend, socket}

[alexeyshch]

Describe the bug
gen_tcp:connect/2 crashes with the following error:

1> gen_tcp:connect(#{port => 80, addr => {127, 0, 0, 1}, family => inet}, [{inet_backend, socket}]). 
** exception error: undefined function gen_tcp_socket:connect/3

Without {inet_backend, socket} it works as expected:

1> gen_tcp:connect(#{port => 80, addr => {127, 0, 0, 1}, family => inet}, []). 
{ok,#Port<0.5>}
