Subject: [PATCH 2/3] ioctl: Fix wrong return case of get_property

If get_property_helper() succeeds in the first time, and then fails in
the next time, then the ret value will not be updated to an error value.
This patch removes 'ret' variable to make 'err' to return being updated
everytime get_property_helper() invoked.
