RDMA/efa: Add support for 128B admin v2 SQ entry

Add the new admin v2 format which is 128B in size and its header extends
the v1 header with checksum and payload version.
On admin SQ init check if the API version reported by the device
supports the admin v2 SQ entry and if so use it. Store the payload
offset and max size in the SQ for quick access in admin command
execution flow.

Using the admin SQ v2 entry implicitly enable the checksum in its
header so set it for device to validate against.
