John Ogness 9bd2f11ac9 printk: Update @console_may_schedule in console_trylock_spinning() 
[ Upstream commit 8076972468 ]

console_trylock_spinning() may takeover the console lock from a
schedulable context. Update @console_may_schedule to make sure it
reflects a trylock acquire.

Reported-by: Mukesh Ojha <quic_mojha@quicinc.com>
Closes: https://lore.kernel.org/lkml/20240222090538.23017-1-quic_mojha@quicinc.com
Fixes: dbdda842fe ("printk: Add console owner and waiter logic to load balance console writes")
