Vasiliy Kulikov b9b1134260 drivers/char/ppdev.c: fix information leak to userland ...

Structure par_timeout is copied to userland with some padding fields
unitialized.  Field tv_usec has type __kernel_suseconds_t, it differs from
tv_sec's type on some architectures.  It leads to leaking of stack memory.
