[PATCH xserver 2/6] xfree86: Fix set but not used warnings in lnx_platform

[Daniel Martin]

Those warnings are generated, when building without systemd support:

../hw/xfree86/os-support/linux/lnx_platform.c: In function ‘get_drm_info’:
../hw/xfree86/os-support/linux/lnx_platform.c:29:16: warning: variable ‘minor’ set but not used [-Wunused-but-set-variable]
     int major, minor, fd;
                ^~~~~
../hw/xfree86/os-support/linux/lnx_platform.c:29:9: warning: variable ‘major’ set but not used [-Wunused-but-set-variable]
     int major, minor, fd;
         ^~~~~

In this case the functions are macros, which don't use theese arguments.

v2: Add comments, why the warnings appear. Suggested by Emil Velikov
