Inserting into g_spdk_lvol_pairs list is done in vbdev_lvs_create_cb, at that point it is known that it can be used. Meanwhile removing was done at start of _vbdev_lvs_remove, to prevent possibility to access it when waiting for destruct callback to complete. This made checking if the g_spdk_lvol_pairs list is empty unreliable to detect if all lvs were destroyed - they could still be being processed and callback not yet called. This patch removes lvs from global list only after the callback of _vbdev_lvs_remove is called. It will be used in future patch during asynchronous finish of vbdev module to determine when all lvs were removed.
