iio: accel: mma8452: switch to non-devm request_threaded_irq()

Avoid using devm_request_threaded_irq() as the driver requires explicit
error-handling path(s). Using devm_* API together with goto-based
unwinding breaks the expected LIFO resource release model.

Add explicit IRQ cleanup in the driver teardown paths to follow kernel
resource management conventions.
