Jason A. Harmening 7b59f7bc5c Use pmap_quick_enter_page() to handle bouncing of unmapped buffers in the x86 busdma_bounce implementation. Also treat user buffers as unmapped. ...

This allows two things:
1. Sync'ing bounced maps in non-sleepable contexts.  The physcopy* calls previously used could sleep on sf_buf operations in some cases.
2. Sync'ing user buffers outside the context of the owning process
