net: bpf: fix compiler warnings in test_bpf

old gcc 4.2 used by avr32 architecture produces warnings:

lib/test_bpf.c:1741: warning: integer constant is too large for 'long' type
lib/test_bpf.c:1741: warning: integer constant is too large for 'long' type
lib/test_bpf.c: In function '__run_one':
lib/test_bpf.c:1897: warning: 'ret' may be used uninitialized in this function

silence these warnings.

Fixes: 02ab695bb37e ("net: filter: add "load 64-bit immediate" eBPF instruction")
