net-mgmt/pmacct: mark unused but set variables with attributes
With clang 13, building net-mgmt/pmacct results in a number of warnings:
netflow9.c:2236:25: error: variable 'tot_len' set but not used [-Werror,-Wunused-but-set-variable]
u_int16_t flows = 0, tot_len = 0;
^
In this particular instance, the 'tot_len' variable does not seem to
have any purpose, nor does it have any further side-effects. There is
one more instance of a set but unused variable 'label' in src/sflow.c,
but the code there is also increasing a byte ptr, so it can't easily be
eliminated. For now mark these variables as unused, with an attribute.
