iio: xilinx-xadc: Remove `irq` field from state struct

Since commit 2a9685d1a3b7 ("iio: adc: xilinx: use more devres helpers and
remove remove()") the `irq` field from XADC driver state struct is only
used in the `probe()` function.

Use the local `irq` variable throughout the `probe()` function and remove
the now unused field from the state struct.
