Fix the locking around nouveau's use of the hmm_range_* APIs. It works
correctly in the success case, but many of the the edge cases have missing
unlocks or double unlocks.

Pull HMM fixes from Jason Gunthorpe:
"Fix the locking around nouveau's use of the hmm_range_* APIs. It works
correctly in the success case, but many of the the edge cases have
missing unlocks or double unlocks.
The diffstat is a bit big as Christoph did a comprehensive job to move
the obsolete API from the core header and into the driver before
fixing its flow, but the risk of regression from this code motion is
low"
* tag 'for-linus-hmm' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma:
nouveau: unlock mmap_sem on all errors from nouveau_range_fault
nouveau: remove the block parameter to nouveau_range_fault
mm/hmm: move hmm_vma_range_done and hmm_vma_fault to nouveau
mm/hmm: always return EBUSY for invalid ranges in hmm_range_{fault,snapshot}
