John Keeping ece8ad75e3 dm verity: fix require_signatures module_param permissions 
[ Upstream commit 0c1f3193b1cdd21e7182f97dc9bca7d284d18a15 ]

The third parameter of module_param() is permissions for the sysfs node
but it looks like it is being used as the initial value of the parameter
here.  In fact, false here equates to omitting the file from sysfs and
does not affect the value of require_signatures.

Making the parameter writable is not simple because going from
false->true is fine but it should not be possible to remove the
requirement to verify a signature.  But it can be useful to inspect the
value of this parameter from userspace, so change the permissions to
make a read-only file in sysfs.
