qed: configure ll2 RoCE v1/v2 flavor correctly

Browse source 
Currently RoCE v2 won't operate with RDMA CM due to missing setting of
the roce-flavour in the ll2 configuration.
This patch properly sets the flavour, and deletes incorrect HSI
that doesn't [yet] exist.

Fixes: abd49676c7 ("qed: Add RoCE ll2 & GSI support")
