Dan Carpenter ef75e14a6c staging: comedi: verify array index is correct before using it 
This code reads from the array before verifying that "trig" is a valid
index.  If the index is wildly out of bounds then reading from an
invalid address could lead to an Oops.

Fixes: a8c66b684efa ("staging: comedi: addi_apci_1500: rewrite the subdevice support functions")
