i386: Never free migration blocker objects instead of sometimes
invtsc_mig_blocker has static storage duration.  When a CPU with
certain features is initialized, and invtsc_mig_blocker is still null,
we add a migration blocker and store it in invtsc_mig_blocker.

The object is freed when migrate_add_blocker() fails, leaving
invtsc_mig_blocker dangling.  It is not freed on later failures.

Same for hv_passthrough_mig_blocker and hv_no_nonarch_cs_mig_blocker.

All failures are actually fatal, so whether we free or not doesn't
really matter, except as bad examples to be copied / imitated.

Clean this up in a minimal way: never free these blocker objects.
