Modified Files:
        src/sys/kern: vfs_bio.c

Log Message:
In bwrite, add assertion that vp != NULL. (vp is the vnode from the
buffer being written.)

There's some logic here that carefully checks for vp being null, and
other logic that will crash if it is. It appears that it's all
needless paranoia. See tech-kern for more info.

Unless someone sees the assertion go off (in which case a lot more
investigation is needed) I or someone will clean out the logic at some
future point.
