Invalid pin reported in gpio callback

[pdunaj]

Describe the bug
The fire_callbacks in gpio_nrfx.c is suppose to notify connected functions that interrupt happened on the GPIO they observe.
There is a bug there - when callback if fired it informs the linked function about all pins that have active isr at the time. In our code we use this information to disable the isr lines for specific pins. Since we can get information about some random pin we may disable callback that somebody else is waiting for.

                if ((cb->pin_mask & pins) & data->int_en) {                                                              
                        __ASSERT(cb->handler, "No callback handler!");                                                   
                        cb->handler(port, cb, pins);                                                                     
                }

the above code should have

                        cb->handler(port, cb, cb->pin_mask & pins);

To Reproduce
Setup two gpio callbacks, one for each pin.

Expected behavior
When callback is fired it should get information about pins it is connected to.

Impact
Showstopper.
