x86: Fix LOCK_PREFIX_HERE for uniprocessor build

Checkin b3ac891b67bd4b1fc728d1c784cad1212dea433d:
x86: Add support for lock prefix in alternatives

... did not define LOCK_PREFIX_HERE in the case of a uniprocessor
build.  As a result, it would cause any of the usages of this macro to
fail on a uniprocessor build.  Fix this by defining LOCK_PREFIX_HERE
as a null string.
