selftests/xsk: Make batch size variable

Browse source

Convert the constant BATCH_SIZE into a variable named batch_size to allow
dynamic modification at runtime. This is required for the forthcoming
changes to support testing different hardware ring sizes.

While running these tests, a bug was identified when the batch size is
roughly the same as the NIC ring size. This has now been addressed by
Maciej's fix in commit 913eda2b08 ("i40e: xsk: remove count_mask").
