ioctl_userfaultfd.2: Drop some unneeded text
...
From a conversation with Mike Rapoport:
What does "consistent" mean?
Actually, I though I've copied this text from Andrea's docs,
but now I've found out it was my wording and I really don't
remember now what was my intention for "consistent" :) My
guess is that I was thinking about atomicity of UFFDIO_COPY,
or the fact that from the faulting thread perspective the
page fault handling is the same whether it's done in kernel
or via userfaultfd... That said, maybe it'd be better just
to drop "in a consistent way".
