mm: allow ->huge_fault() to be called without the mmap_lock held
Remove the checks for the VMA lock being held, allowing the page fault
path to call into the filesystem instead of retrying with the mmap_lock
held. This will improve scalability for DAX page faults. Also update the
documentation to match (and fix some other changes that have happened
recently).
