Jeff Roberson 8264830c95 Some refactoring of the buf/vm interface. ...

- Eliminate bogus page replacement that is inconsistently applied in the
   invalidation loop in brelse.  This has been a no-op in modern times as
   biodone() is responsible for cleaning up after bogus pages.  This
   would've spammed the console with printfs at a minimum.
 - Allow the compiler and human readers alike to reason about allocbuf()
   by splitting it into constituent parts.
 - Separate the VM manipulating and buf manipulating code in brelse() and
   bufdone() so that the intentions are clear.  This makes it evident that
   there are several duplicated buf pages loops that will be consolidated
   at a later time.
