[igt-dev] [PATCH v2 2/4] tests/amdgpu/amd_psr: set visual-confirm option required argument

[David Zhang]

[why & how]
previously set to optional argument, and the command line argument
set for visual confirm debug option would cause NULL optarg string
and thus hit system segmentation fault.

set the "visual-confirm" from optional to required argument.
