[igt-dev] [PATCH i-g-t 6/7] lib/igt_fb: Function to create a bo for passed in igt_fb

[Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com>]

In order to execute negative tests that validate fb creation, tests need to
be able to call the addfb ioctl themselves so that the arguments can be
manipulated. Add a library function to provide an initialized fb without
registering the fb with the kernel.
