media: pci/ivtv: remove FOLL_FORCE usage
FOLL_FORCE is really only for ptrace access. R/O pinning a page is
supposed to fail if the VMA misses proper access permissions (no VM_READ).
Let's just remove FOLL_FORCE usage here; there would have to be a pretty
good reason to allow arbitrary drivers to R/O pin pages in a PROT_NONE
VMA. Most probably, FOLL_FORCE usage is just some legacy leftover.
