Update all struct proto_ops connect() callback function prototypes from
"struct sockaddr *" to "struct sockaddr_unsized *" to avoid lying to the
compiler about object sizes. Calls into struct proto handlers gain casts
that will be removed in the struct proto conversion patch.
No binary changes expected.

The RDMA CM module might invoke erdma_create_ah() or erdma_destroy_ah()
in a non-sleepable context. Both of these functions will call the
erdma_post_cmd_wait(), which can potentially sleep and occasionally lead
to a hard lockup. Therefore, post the create_ah and destroy_ah commands in
polling mode if the RDMA_CREATE_AH_SLEEPABLE and RDMA_DESTROY_AH_SLEEPABLE
flags are not set, respectively.

Since the netdev events of link status is now handled in ib_core,
remove the related code in drivers.
In addition, remove dev->state as it is only used in erdma_query_port(),
and it can be replaced by ib_get_curr_port_state().

Currently, the erdma driver supports both the iWARP and RoCEv2 protocols.
The erdma driver reads the ERDMA_REGS_DEV_PROTO_REG register to identify
the protocol used by the erdma device. Since each protocol requires
different ib_device_ops, we introduce the erdma_device_ops_iwarp and
erdma_device_ops_rocev2 for iWARP and RoCEv2 protocols, respectively.

The original doorbell allocation mechanism is complex and does not meet
the isolation requirement. So we introduce a new doorbell mechanism and the
original mechanism (only be used with CAP_SYS_RAWIO if hardware does not
support the new mechanism) needs to be kept as simple as possible for
compatibility.
