levi.yun d286c4cfa3 trace/pid_list: Change gfp flags in pid_list_fill_irq() ...

commit 7dc836187f7c6f70a82b4521503e9f9f96194581 upstream.

pid_list_fill_irq() runs via irq_work.
When CONFIG_PREEMPT_RT is disabled, it would run in irq_context.
so it shouldn't sleep while memory allocation.

Change gfp flags from GFP_KERNEL to GFP_NOWAIT to prevent sleep in
irq_work.

This change wouldn't impact functionality in practice because the worst-size
is 2K.
