drm-lease-v1: fix error codepath

Browse source 
We were crashing in the error codepath [1] when
wlr_drm_create_lease() fails.

To fix this, delay the creation of the wlr_drm_lease_v1 until the
request is granted. Previously we were allocating that struct early
without populating the drm_lease field. However that means we ended
up with a half-constructed struct in the error codepath which is
annoying to handle.
