Luke Wang 4d9adcb94d Bluetooth: btnxpuart: Shutdown timer and prevent rearming when driver unloading
[ Upstream commit 0d0df1e750bac0fdaa77940e711c1625cff08d33 ]

When unload the btnxpuart driver, its associated timer will be deleted.
If the timer happens to be modified at this moment, it leads to the
kernel call this timer even after the driver unloaded, resulting in
kernel panic.
Use timer_shutdown_sync() instead of del_timer_sync() to prevent rearming.
