kernel - Check B_NOTMETA in buffer release code
* When releasing the VM pages backing a buffer cache buffer if B_NOTMETA
is set on the buffer attempt to move the pages to the VM page cache
instead of leaving them on the active or inactive queue.
* This partially deals with the double data caching which occurs when
HAMMER's double_buffer mode is enabled by shortening the life of
the pages backing the secondary buffer(s).
