eMBPoll: return internal failures

Status flags are returned by the internal peMBFrameReceiveCur and peMBFrameSendCur handlers, but were being ignored, with the function simply always returning MB_ENOERR unless the entire eMBState was invalid. This should allow better stats collecting from the outside of eMBPoll Fixes: cwalter-at#8 Signed-off-by: Karl Palsson <[email protected]>
