RDMA/mlx5: Initiate dropless RQ for RAW Ethernet functions 

[ Upstream commit ee4d269ecc ]

Delay drop data is initiated for PFs that have the capability of
rq_delay_drop and are in roce profile.

However, PFs with RAW ethernet profile do not initiate delay drop data
on function load, causing kernel panic if delay drop struct members are
accessed later on in case a dropless RQ is created.

Thus, stage the delay drop initialization as part of RAW ethernet
PF loading process.
