[PATCH] selftests: bpf: xskxceiver: ksft_print_msg: fix format type error

[Anders Roxell]

Crossbuilding selftests/bpf for architecture arm64, format specifies
type error show up like.

xskxceiver.c:912:34: error: format specifies type 'int' but the argument
has type '__u64' (aka 'unsigned long long') [-Werror,-Wformat]
 ksft_print_msg("[%s] expected meta_count [%d], got meta_count [%d]\n",
                                                                ~~
                                                                %llu
                __func__, pkt->pkt_nb, meta->count);
                                       ^~~~~~~~~~~
xskxceiver.c:929:55: error: format specifies type 'unsigned long long' but
 the argument has type 'u64' (aka 'unsigned long') [-Werror,-Wformat]
 ksft_print_msg("Frag invalid addr: %llx len: %u\n", addr, len);
                                    ~~~~             ^~~~

Fixing the issues by using the proposed format specifiers by the
compilor.
