[Patch] BaseTools/GenFds: Remove redundant GetRealFileLine call

[Yonghong Zhu <yonghong.zhu@intel.com>]

From: Zurcher, Christopher J <christopher.j.zurcher@intel.com>

The EvaluateConditional function should not call GetRealFileLine
because this is already done in Warning init and only needs to be
calculated in the event of a parsing failure. This fix stops
InsertedLines from being subtracted twice during error handling.
