Subject: [PATCH bpf-next v2 03/15] selftests/xsk: submit correct number of frames in populate_fill_ring

From: Magnus Karlsson <magnus.karlsson@...el.com>

Submit the correct number of frames in the function
xsk_populate_fill_ring(). For the tests that set the flag
use_addr_for_fill, uninitialized buffers were sent to the fill ring
following the correct ones. This has no impact on the tests, since
they only use the ones that were initialized. But for correctnes, this
should be fixed.
