1deeb6dd84 Check socket binding result before doing anything with socket. (This is to address ARG findings.) Breaking the single return rule here, due to precedent violation at line 1039 and 1144. 
prvTransferConnect() now returns:
- pdTRUE: everything's good. pdTRUE = 1.
- -pdFREERTOS_ERRNO_ENOMEM: FreeRTOS_socket() failed. -pdFREERTOS_ERRNO_ENOMEM = -12.
- -pdFREERTOS_ERRNO_EINVAL || -pdFREERTOS_ERRNO_ECANCELED: FreeRTOS_bind() failed. Negative values.

Thus, at line 569 and line 617, needs to check != pdTRUE instead of == pdFALSE.
