myri10ge: update firmware headers to 1.4.37

Update myri10ge firmware headers to 1.4.37:
* Make each member of the error/cmd enum an initialized one, so there
  is a convenient numerical reference to look for reverse conversion.
* Add new MXGEFW_CMD_RELAX_RXBUFFER_ALIGNMENT command.
* Add new "features" field to mcp_header.
