iio: pressure: bmp280: Tolerate IRQ before registering
With DEBUG_SHIRQ enabled we have a kernel crash
[ 116.482696] BUG: kernel NULL pointer dereference, address: 0000000000000000
...
[ 116.606571] Call Trace:
[ 116.609023] <IRQ>
[ 116.611047] complete+0x34/0x50
[ 116.614206] bmp085_eoc_irq+0x9/0x10 [bmp280]
because DEBUG_SHIRQ mechanism fires an IRQ before registration and drivers
ought to be able to handle an interrupt happening before request_irq() returns.
Fixes: aae953949651 ("iio: pressure: bmp280: add support for BMP085 EOC interrupt")
