[PATCH] arch: x86: kernel: fixed unused label issue
...if directive just after that label fixes the issue.
In addition,there are three errors reported by checkpatch script
on this file. This commit fixes two of them. The last one is
ERROR: Macros with multiple statements should be enclosed
in a do - while loop
which probably is a false alarm here as PATCH_SITE macro defines
a case in switch local to native_patch function not meant to be used
in other places.
