[PATCH v3 3/3] Input: ad7897 - use separate error handling for different allocators

[Andi Shyti <andi@etezian.org>]

Split the error between devm_kzalloc and
devm_input_allocate_device, there is no need to call the second
allocator if the first has failed. Besides this doesn't provide
practical advantages.
