[PATCH v2 01/12] gpib: agilent_82350b: Unify *allocate_private

["Dominik Karol Piątkowski" <dominik.karol.piatkowski@protonmail.com>]

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.
