[PATCH 5.15 679/917] powerpc/xmon: fix task state output

[Greg Kroah-Hartman]

From: Denis Kirjanov <kda@xxxxxxxxxxxxxxxxx>

[ 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")
