The migrate_add_blocker() function documents that if it fails it will
free the Error it is passed via its reasonp argument and set reasonp
to NULL.  That means that in kvm_arm_enable_mte() we don't need to
call error_free(mte_migration_blocker) in the failure codepath.
Doing so is harmless because error_free(NULL) is permitted and does
nothing, but we can remove the unnecessary code.
