qlxgbe: add GCC_MS_EXTENSIONS to CFLAGS to make old base GCC happy
The module uses unnamed structure and union fields and base GCC in stable/10 doesn't like it. I think that that is a C11 feature, so it is courteous of more modern compilers to not complain about it when compiling in C99 mode.
This is a direct commit as the change is not required in head.
