Subject: [PATCH v2 10/12] gpib: ni_usb: Unify *allocate_private

Return values for *allocate_private functions as well as calling code in
gpib driver are all over the place. Unify them by returning -errno if
something fails, zero otherwise. Use the returned value as early return
value in case of error. Replace kmalloc/memset pairs to kzalloc.

v2: Replace kmalloc/memset pairs to kzalloc.
