Hi Steve,

The samples/bluetooth/mesh fails on my nrf52840_pca10056

Below is the debug output of both the failing and non-failing cases.

I bisected down to:
first bad commit: [aaeff3c165051c15dfa025f1aad82f333395b6d0] 
Bluetooth: Add basic host-side support for HCI vendor extension

Somewhere CONFIG_BT_HCI_VS_EXT defaults to "y". If I set it to "n" in prj.conf, all is well.

I went through the patch in question, and found a leak of a net_buf
object. I wonder if the available buffer count has been so well
fine-tuned that loosing just one causes this issue. Anyway, could you
please try the attached patch (while keeping CONFIG_BT_HCI_VS_EXT=y).
Thanks.

Johan
