MdeModulePkg: Correct one return status code in SNP Transmit function.

According to UEFI spec, a BUFFER_FULL return status in UNDI Transmit command
indicates UNDI "Transmit buffer is full. Call Get Status command toempty
buffer." So this patch updates the SNP Transmit to return EFI_NOT_READY for
BUFFER_FULL to let the call know the buffer full status.
