fix(ringbuf): xRingbufferReceive() crashes for allow-split buffers

Browse Source 
This commit adds an assert check to xRingbufferReceive() and
xRingbufferReceiveFromISR() functions to prevent them from being used to
retrieve items from an allow-split buffer. Corresponding documentation
has also been updated.
