[PATCH 2/2] drm/xe/guc: Refine CT queue checks and log formatting

[Shuicheng Lin <shuicheng.lin@intel.com>]

Fix three code-level cleanups in xe_guc_ct.c:

- Use SZ_4K for the queue size alignment assertion in
  xe_guc_ct_queue_proc_time_jiffies().
- Drop an unused local variable in guc_ct_send_wait_for_retry().
- Add missing trailing newlines in CT error/warn log messages.

These changes keep behavior unchanged while improving correctness checks
and log formatting.
