devfs - Fix FREEBLKS
* Since vn and md were changed to use the disk subsystem they
essentially haven't been able to receive any BUF_CMD_FREEBLKS since
their D_CANFREE flag was not propagated through the disk subsystem.
* Fix this by making the flag specific to the device via SI_CANFREE and
propagating the D_CANFREE of even *underlying*/covered devices to the
top-level device's SI_CANFREE.
