stable inclusion from linux-4.19.155 commit 36beb0e4d553671273710890e9357aaebc996f36
--------------------------------
commit fea456d82c19d201c21313864105876deabe148b upstream.
This was adding size to start, but pfn and start are in pages, so it should be using num_pages.
Not sure this fixes anything in the real world, just noticed it during refactoring.
