Alexander Kabaev 31932fae1e Do not pass unmapped buffers to drivers that cannot handle them ... In physio, check if device can handle unmapped IO and pass an appropriately mapped buffer to the driver strategy routine. The only driver in the tree that can handle unmapped buffers is one exposed by GEOM, so mark it as such with the new flag in the driver cdevsw structure. This fixes insta-panics on hosts, running dconschat, as /dev/fwmem is an example of the driver that makes use of physio routine, but bypasses the g_down thread, where the buffer gets mapped normally.
