USB: usbfs: don't leak kernel data in siginfo
When a signal is delivered, the information in the siginfo structure
is copied to userspace. Good security practice dicatates that the
unused fields in this structure should be initialized to 0 so that
random kernel stack data isn't exposed to the user. This patch adds
such an initialization to the two places where usbfs raises signals.
