[igt-dev] [PATCH i-g-t v3 1/4] lib/ioctl_wrapper: use defines for get_param instead of param number

[Lukasz Kalamarz <lukasz.kalamarz@intel.com>]

In lib code there were few functions using param number instead of
defines. This could lead to some issues (i.e. stolen support
pointing on different parameter) and we would like to avoid them.
v2: Rebased patch
