[PATCH i-g-t 2/4] lib/igt_sysfs: Fix close when rebinding

[Lucas De Marchi <lucas.demarchi@intel.com>]

This function could be de-multiplexed and use single functions to each
action (e.g. igt_kmod_unbind already exists). However, with the aim of
simply fixing the bug, make sure the fd is closed with
__drm_close_driver(), otherwise the cached fd is not invalidated and
later drm_open_driver() fails because the driver is considered already
opened.
