55b48e23f5c4 ("genirq/devres: Add error handling in devm_request_*_irq()")
added automatic error logging to devm_request_threaded_irq() and
devm_request_any_context_irq() via the new devm_request_result() helper,
which prints device name, IRQ number, handler functions, and error code
on failure.

Since devm_request_irq() is a static inline wrapper around
devm_request_threaded_irq(), it also benefits from this
automatic logging.

Remove the now-redundant dev_err() and dev_err_probe() calls
in watchdog drivers that follow these devm_request_*_irq()
functions, as the core now provides more detailed diagnostic
information on failure.
