drivers: watchdog: siwx91x: Fix pause in sleep

The watchdog timer on SiWx91x devices is designed to
pause during deep-sleep and resume after wakeup.
However, an incorrect check in`wdt_setup` was
preventing this intended behavior. This patch removes
the check, restoring the correct pause-in-sleep
functionality.
