    staging: gpib: fix unset padding field copy back to userspace

    The introduction of a padding field in the gpib_board_info_ioctl is
    showing up as initialized data on the stack frame being copyied back
    to userspace in function board_info_ioctl. The simplest fix is to
    initialize the entire struct to zero to ensure all unassigned padding
    fields are zero’d before being copied back to userspace.
