um: Remove unused ipi_pipe field from cpuinfo_um

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

It's no longer used after the removal of the SMP implementation in
TT mode by commit 28fa468f5316 ("um: Remove broken SMP support").

While at it, remove the outdated comment.
