selftests/xsk: Introduce set_ring_size function with a retry mechanism for handling AF_XDP socket closures
Introduce a new function, set_ring_size(), to manage asynchronous AF_XDP
socket closure. Retry set_hw_ring_size up to SOCK_RECONF_CTR times if it
fails due to an active AF_XDP socket. Return an error immediately for
non-EBUSY errors. This enhances robustness against asynchronous AF_XDP
socket closures during ring size changes.
