Subject: [PATCH AUTOSEL 6.12 407/486] wifi: rtw89: coex: Assign value over than 0 to avoid firmware timer hang

From: Ching-Te Ku <ku920601@...ltek.com>

[ Upstream commit 2e4c4717b3f6f019c71af984564b6e4d0ae8d0bd ]

If the slot duration is 0, the firmware timer will trigger timer hang at
the timer initializing state in a low rate due to hardware algorithm.
