drm/radeon: Fix stack data leak
Always zero-init a structure on the stack which is returned by a
function. Otherwise you may leak random stack data from previous
function calls.
This fixes the following warning I was seeing:
CC [M] drivers/gpu/drm/radeon/radeon_atombios.o
drivers/gpu/drm/radeon/radeon_atombios.c: In function "radeon_atom_get_hpd_info_from_gpio":
drivers/gpu/drm/radeon/radeon_atombios.c:261: warning: "hpd.plugged_state" is used uninitialized in this function
