Also introduce get_user_page_fast_only(), and use it in a few
places that hard-code nr_pages to 1.

There is an existing bug when vm_insert_pfn() can return
ENOMEM which was ignored and VM_FAULT_NOPAGE returned as
default. The new inline vmf_insert_pfn() has removed
this inefficiency by returning correct vm_fault_ type.

We are fixing a minor bug, that the error from vm_insert_
pfn() was being ignored and the effect of this is likely
to be only felt in OOM situations.

previously cxl_mmap_fault returns VM_FAULT_NOPAGE as
default value irrespective of vm_insert_pfn() return
value. This bug is fixed with new vmf_insert_pfn()
which will return VM_FAULT_ type based on err.
