Davidlohr Bueso b95df5e3e4 drivers/IB,core: reduce scope of mmap_sem
ib_umem_get() uses gup_longterm() and relies on the lock to stabilze the
vma_list, so we cannot really get rid of mmap_sem altogether, but now that
the counter is atomic, we can get of some complexity that mmap_sem brings
with only pinned_vm.
