2f04381aeb extmod/modlwip: Fix crash when calling recv on listening socket. 
Add check to prevent calling recv on a socket in the listening state.  This
prevents a crash/hard fault when user code mistakenly tries to recv on the
listening socket instead of on the accepted connection.

Add corresponding test case to demonstrate the bug.

beeb250d58 tests/multi_net: Fix TCP accept test when using system error numbers. 
If a port is not using internal error numbers, which match both lwIP and
Linux error numbers, ENTOCONN from standard libraries errno.h equals 128,
not 107.
