Set zvol_major/zvol_threads permissions

Browse Source 
The zvol_major and zvol_threads module options were being created
with 0 permission bits.  This prevented them from being listed in
the /sys/module/zfs/parameters/ directory, although they were
visible in `modinfo zfs`.  This patch fixes the issue by updating
the permission bits to 0444.  For the moment these options must
be read-only because they are used during module initialization.
