Otherwise things like module unloading can lead to dangling function pointers, or worse. The IB MR code is the only place that calls this function and had a really poor attempt at creating this fence. Provide a good version in the core code as future patches will add more places that need this fence.

PDDR register can only be queried when PCAM register reports it as supported in its register mask. A new helper macro was added to the MLX5_CAP_* infrastructure in order to access this mask.

Implement a mechanism using EPOCH(9) which allows us to make the callback path for completion events mostly lockless. Simplify draining callback events using epoch_wait(). While at it make sure all receive completion callbacks are covered by the network EPOCH(9), because this is required when calling if_input() and ether_input() after r357012.
