The current semantics of do_resq() is to do a intptr_t type store in
successful cases, however, in test_percpu_{inc,spinlock}, we use
test_data_entry::count as the location to store, whose type is int.
intptr_t and int have different size on LP64 systems, and despite the
inconsistency of types, having test_data_entry::count as int needs more
care on endian handling.
To make things simpler and more consistent, convert
test_data_entry::count to type intptr_t, which also makes the coming
tests for ppc64le and ppc64 share the same code.
