trafgen: sparse: make seed static
sparse reported that the variable seed can be made static: trafgen.c:110:14: warning: symbol 'seed' was not declared. Should it be static? While at it, also rename a local variable 'seed' to not overlap contexts. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
