iio: mma8452: Use correct type for return variable in IRQ handler

Browse Source 
The IRQ handler's return type is irqreturn_t. The mma8452 uses a variable
to store the return value, but the variable is of type int. Change this to
irqreturn_t. This makes it easier to verify that the code is correct.
