hammer2 - Improve swapcache support

* Properly set B_NOTMETA on media buffers, which allows swapcache to
  distinguish between data and meta-data buffers.

  This ensures that a user desiring to only swapcache meta-data does
  not blow all the SSD swap on file data, particularly if there is an
  excessive amount of file data.

* Greatly improves bulkfree performance on hard drives when SSD swapcache
  is enabled for meta-data only.
