If the named semaphore is already open, sem_open() only increments a
reference count and did not take the flags into account (which otherwise
happens by passing them to open()). Add an extra check for O_CREAT|O_EXCL.

HT frames are now correctly protected with an RTS and for the AR5416,

* Doubly/triply ensure that the aggregate frames are being limited to

if any subframes in an aggregate have different protection from the
first frame in the formed aggregate, don't add that frame to the
aggregate.
This is likely a suboptimal method (I think we'll mostly be OK marking
frames that have seqno's with the same protection as normal data frames)
but I'll just be cautious for now.
This will be used by some upcoming code to ensure that aggregates
are enforced to be a certain size. The AR5416 has a limitation on
RTS protected aggregates (8KiB).
