[PATCH v2] gpiolib: fix incorrect IRQ requesting of an active-low lineevent

When a pin is active-low, logical trigger edge should be inverted to match the same interrupt opportunity. For example, a button pushed triggers falling edge in ACTIVE_HIGH case; in ACTIVE_LOW case, the button pushed triggers rising edge. For user space the IRQ requesting doesn't need to do any mo
