Description

While testing lnet sysfs patches, it is found that  lctl list_param -R does not display everything under sysfs tree.

The lnet-sysfs hierarchy is something like - 
/sys/fs/lnet/net/o2ib1/ib0

But lctl list_param -R does not display anything beyond
/sys/fs/lnet/net

This is because of the below code in param_display function in  - 

tmp = strstr(paths.gl_pathv[i], param_name);

Here instead of param_name, it should be /param_name/
