iio: hid_Sensors: fix crash during trigger unregister
commit ec7f68e07bf10198717b7824c78201b46bbf1956 upstream.
We can't store the trigger instance created by iio_trigger_alloc, in
trig field of iio_device structure. This needs to be stored in the
driver private data. Othewise it can result in crash during module
unload. Hence created a trig_ptr in the common data structure
for each HID sensor IIO driver and storing here.
