Add aeth name syndrome decode to enhance debugging.

The IBTA RC ACK contains an ACK extended transport header.

Part of that header is the syndrome field that qualifies the RC ACK as an
ACK, NAK, or RNR NAK.

Without the patch here is the syndrome decode:
aeth syn 0x00

Here is the decode with the fix:
aeth syn 0x00 ACK

Using fence->status to determine whether or not there are callbacks
remaining on the sync_fence is racy since fence->status may have been
decremented to 0 on another CPU before fence_check_cb_func() has
completed.  By unconditionally calling fence_remove_callback() for each
fence in the sync_fence, we guarantee that each callback has either
completed (since fence_remove_callback() grabs the fence lock) or been
removed.
