Update unused headers and NULL checks for platform wrappers (#367)

Browse source 
- Remove unused headers in the plaintext FreeRTOS sockets wrapper
- Update MFLN even though the preceding optional configuration returned an mbedTLS error
- Remove an unused `NULL` check in a private method that is already checked by the public connect method
- Add a `NULL` check to the public disconnect method
