net/ark: fix index arithmetic

Behavior for signed integer overflow is not defined which can causes
undesired behavior at values near max and min bounds.
The used of unsigned is defined as to use modulo arithmetic which is the
desired behavior.
This patch replaces int32_t with uint32_t except for necessary casts.

drivers: move alignment attribute on types for MSVC

Move location of __rte_aligned(a) to new conventional location. The new
placement between {struct,union} and the tag allows the desired
alignment to be imparted on the type regardless of the toolchain being
used for both C and C++. Additionally, it avoids confusion by Doxygen
when generating documentation.

Add unique dev_private data for each port to manage queue assignment.

This patch repairs a latent issue uncovered during testing.
