lustre_tools.c: protect againt IOC_MDC_GETFILEINFO_V1 redefinition

[cedeyn]

With lustre-2.15, IOC_MDC_GETFILEINFO_V1 is already declared in header file. This patch avoid compilation issue against more recent lustre version.

I was thinking defining something unique. Like RH_IOC_MDC_GETFILEINFO_V1 to avoid the repeat of name clash which happened when lustre used the same name. We deleted the whole section as we knew it was not the old version. However, this approach is good too.

It seems a patch already exists with the same idea :) https://review.gerrithub.io/c/cea-hpc/robinhood/+/541134

It should be merged soon.
