drm/i915: make i915_drm_client_fdinfo() reference conditional again
The function is only defined if CONFIG_PROC_FS is enabled: ld.lld: error: undefined symbol: i915_drm_client_fdinfo >>> referenced by i915_driver.c >>> drivers/gpu/drm/i915/i915_driver.o:(i915_drm_driver) in archive vmlinux.a Use the PTR_IF() helper to make the reference NULL otherwise.
