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.
