Subject: [PATCH 5.14 652/849] powerpc/xmon: fix task state output

From: Denis Kirjanov <kda@...ux-powerpc.org>

[ Upstream commit b1f896ce3542eb2eede5949ee2e481526fae1108 ]

p_state is unsigned since the commit 2f064a59a11f

The patch also uses TASK_RUNNING instead of null.

Fixes: 2f064a59a11f ("sched: Change task_struct::state")
