[RFC PATCH v1 01/10] KVM: guest_memfd: Don't set FGP_ACCESSED when getting folios

[Ackerley Tng <ackerleytng@google.com>]

guest_memfd folios don't care about accessed flags since the memory is
unevictable and there is no storage to write back to, hence, cleanup the
allocation path by not setting FGP_ACCESSED.
