Now that a list of pages is deduplicated at once, the TLB flush can be
batched for all vmemmap pages that got remapped.

Expand the flags field value to pass whether to skip the TLB flush on
remap of the PTE.

The TLB flush is global as we don't have guarantees from caller that the
set of folios is contiguous, or to add complexity in composing a list of
kVAs to flush.

Modified by Mike Kravetz to perform TLB flush on single folio if an
error is encountered.
