But the loop is in alloc_heap_pages() --- where else would you be testing?

Commit 63e8a1e5ffa7a7fdbde887805f673fea7e8d2e94 ("xen: check parameter
validity when parsing command line") introduced a bug for the case
when a boolean parameter was specified by its keyword only (no value).
It would set just the wrong boolean value for that parameter.

With a 64bit hypervisor there are no conditional l3 slots, and this is
unlikely to change moving forwards.
No functional change (as confirmed by diffing the disassembly. GCC obviously
already optimised this code away.)
