Eliminate page queues locking from bufdone_finish() through the

following changes:

Rename vfs_page_set_valid() to vfs_page_set_validclean() to reflect
what this function actually does.  Suggested by: tegge

Introduce a new version of vfs_page_set_valid() that does no more than
what the function's name implies.  Specifically, it does not update
the page's dirty mask, and thus it does not require the page queues
lock to be held.

Update two of the three callers to the old vfs_page_set_valid() to
call vfs_page_set_validclean() instead because they actually require
the page's dirty mask to be cleared.

Introduce vm_page_set_valid().
