0f8f88ca46 hfi1/user_exp_rcv/invalid: Remove function 
user_exp_rcv_invalid is only used together with the mmu cache
(its purpose is the delayed freeing of tids that were invalidated in cache)

Since we do not use that cache, the function can go

e64d89cd48 hfi: bases for user_exp_rcv 
This implements a skeleton setup function and call it on ioctl

Many missing points:
 - missing pci mapping to make setup work
 - no clear (passed to linux, so will likely bug out)
 - missing locks/safe-guards

7366da4390 Fix other warnings 
Most were harmless, but the change to ACCESS_ONCE from volatile
cast is probably useful.
Expanding macro, we basically went from:
    m = (volatile struct sdma_vl_map *)dd->sdma_map;
to
    m = *(volatile struct sdma_vl_map **)&(dd->sdma_map);
i.e. the explicit lookup is at a different level.
