Roland Dreier ea98054fef mlx4_core: Change capability decoding: SRC->XRC 
The SRC ("scalable RC") transport has been renamed to XRC ("extended 
RC"), to avoid having an abbreviation that is so easily confused with an 
abbreviation for "source."  Update the HCA capability decoding output to 
use the new name.
