[llvm-profdata] Make sure to consume Error on the error path of setIsIRLevelProfile

Browse Source 
Encountered a crash while running a debug build, where this code path would be taken due to a mismatch in profile coverage data versions. Without consuming the error, an assert would be triggered inside the destructor of Error.
