[PATCH 2/5] EDAC/skx_common: Delete duplicated and unreachable code

[Qiuxu Zhuo]

skx_mce_check_error() returns early if the error isn't from memory.
So when skx_mce_output_error() is invoked from skx_mce_check_error(),
it doesn't need to re-check whether the error is from memory. Delete
the duplicated and unreachable code from skx_mce_output_error().
