[ofw] [PATCH] opensm: ignore and overwrite corrupted guid2lid file

[Yevgeny Kliteynik]

Tzachi,

When Windows is crashing with BSOD, it might corrupt files that were
previously opened for writing, even if the files are closed. As a result,
we might see corrupted guid2lid file, and OpenSM will exit on such error.
This patch makes SM ignore (and later overwrite) corrupted guid2lid files.
