[PATCH v2] iio: buffer: fix warning in requesting threaded irq

[Junxiao Chang]

IRQF_ONESHOT is for threaded IRQ. If there is no threaded IRQ
handler, this flag should not be set.

This change fixes a warning during booting with kernel v7.0-rc3:

WARNING: kernel/irq/manage.c:1502 at __setup_irq+0x1639/0x2510, CPU#3: iio-sensor-prox/974
RIP: 0010:__setup_irq+0x1639/0x2510

v2: using ternary and drop temp variable
