[PATCH] discover/boot: Fix talloc parent for resource URLs

[Samuel Mendoza-Jonas]

The pb_urls for the boot resources use 'opt' as the talloc parent but
this may be NULL, for example if this is a user-created boot option.
Move the boot_task initialisation so it can be used as the talloc parent
instead.
