kern_poll: Restore explanatory comment removed in r177374

2018-11-01T23:46:23Z

The comment isn't stale. The check is bogus in the sense that poll(2) does not require pollfd entries to be unique in fd space, so there is no reason there cannot be more pollfd entries than open or even allowed fds. The check is mostly a seatbelt against accidental misuse or abuse. FD_SETSIZE, while usually unrelated to poll, is used as an arbitrary floor for systems with very low kern.maxfilesperproc. Additionally, document this possible EINVAL condition in the poll.2 manual. No functional change.
