zev: workaround: mount cb bails for failed mount
The zev mount callback got called for failed mounts, which then
crashed the system when the callback tried to access zfsvfs data.
A fix in zfs_mount() was written, but since updating the zfs module
is painful we also work around this problem from inside the callback,
so that only the zev module needs to be updated.
Seperate commit so it can be backported to earlier titanic releases.

zev: dynamically create temporary queues
The zev driver can now create new ephemeral queues in the fly.
When the tmpqueue device is opened, a new non-persistent queue
is created and the userland can immediatly use it as though
the tmpqueue device itself was a valid queue device. As soon
as the device is closed the temporary queue is removed.
This should make using tmp queues easier. It is no longer
necessary to find or generate a free queue name, and tmp queues
opened via the tmpqueue device can not be orphaned - they are
already opened when they are created. Using the old method
a userland process might crash or forget about a tmp queue
it has created - which would then remain in the queue list
indefinitly.
