You could only lock newfdp #ifdef INVARIANTS perhaps since that is the only 
reason you are doing it.  That doesn't pessimize production kernels while 
still letting your assertions work ok.  You could also perhaps tweak the 
mtx_assert to somehow check the state of the fd pointer to see if it is a new 
table (refcount of 0 or some such)
