[PATCH v2 08/12] gpib: hp_82341: Unify *allocate_private

[Dominik Karol Piątkowski]

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.
