iio: pressure: bmp280: fix runtime suspend/resume crash
In commit 3d838118c6aa ("iio: pressure: bmp280: add power management")
For some reason the code in the runtime suspend/resume hooks
got wrong (I suspect in the ambition to cut down boilerplate)
and it seems it was tested without CONFIG_PM and crashes like
so for me:
Unable to handle kernel NULL pointer dereference at virtual address 0000000c
pgd = c0204000
[0000000c] *pgd=00000000
Internal error: Oops: 5 [#1] PREEMPT SMP ARM

Hardware name: Generic DT based system

PC is at regulator_disable+0x0/0x6c
LR is at bmp280_runtime_suspend+0x3c/0xa4
Dereferencing the BMP280 state container properly fixes the problem,
sorry for screwing up.
