IB/hfi1: Search shared contexts on the opened device, not all devices
The search for available shared contexts walks each registered hfi1
device. This search is too broad because other devices may not
be on the same fabric, and using its contexts could cause unexpected
behavior.
Removed walking the list of devices, limiting the search to the opened
device. With the device walk removed, the hfi1_devdata (dd) is not
available. Added it to the hfi1_filedata for reference.
With this change, hfi1_count_units() was rendered obsolete and was
removed.
