vnconfig: Improve recent caching edit to man page

Explain that typical usage patterns don't run into consistency issues.
Xref the -i flag.

Leave ambiguous the nature of cache inconsistency, because I don't
undersstand it and it's best not to make it a defined interface
anyway. I am unclear on whether a buffer cache read before a vnd
session might persist after a vnd is configured/used/unconfigured, and
whether a buffer cache write might be delayed until after a vnd
configure/write.

vnconfig: Add caution to man page about cache bypassing behavior

Add magic incantation to configure an image for mount_udf(8).

Fix typo; from SAITOH Masanobu <msaitoh@spa.is.uec.ac.jp> in PR misc/3796.

Revert previous change that accepts non-raw devices as argument. The
distrib Makefiles have been adjusted appropriately. This change made
block devices and char devices look the same to the naive user, and
it is not appropriate.
