gpiolib: fix filtering out unwanted events
GPIOEVENT_REQUEST_BOTH_EDGES is not a single flag, but a binary OR of GPIOEVENT_REQUEST_RISING_EDGE and GPIOEVENT_REQUEST_FALLING_EDGE. The expression 'le->eflags & GPIOEVENT_REQUEST_BOTH_EDGES' we'll get evaluated to true even if only one event type was requested. Fix it by checking both RISING & FALLING flags explicitly.
