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.
