[PATCH 04/10] ioctl_userfaultfd.2: fix a few trivial mistakes

- Fix missing paragraph tag. The lack of this tag yielded no blank line
in the rendere dpage, which is inconsistent with style elsewhere.

- The description of UFFDIO_WRITEPROTECT was a sentence fragment; the
last half of the sentence was left out by mistake. Add it in to fix
the issue.

- move UFFDIO_WRITEPROTECT 'since' to its own line All other ioctls
note the kernel version introduced on a separate line from the ioctl
name. Update UFFDIO_WRITEPROTECT to match the existing style.
