irda: do not leak initialized list.dev to userspace

list.dev has not been initialized and so the copy_to_user is copying
data from the stack back to user space which is a potential
information leak. Fix this ensuring all of list is initialized to
zero.

Detected by CoverityScan, CID#1357894 ("Uninitialized scalar variable")
