fix(i2c_master): yield from ISR when no matching device is found

`i2c_master_isr_handler_default()` may set HPTaskAwoken to pdTRUE via
`xQueueSendFromISR()` (event_queue), `xSemaphoreTakeFromISR()` and
`xSemaphoreGiveFromISR()` on `bus_lock_mux`. When the device list lookup
returns no matching device, the function returned directly, skipping
the `portYIELD_FROM_ISR()` at the bottom of the handler. A higher-
priority task waiting on the bus mux or the event queue would then have
to wait for the next scheduler tick instead of being preempted into
immediately, inflating worst-case event latency.

Replace the early return with a goto to the existing yield check at the
end of the ISR.
