gcc 10.0.1 reports:
../examples/ipsec-secgw/ipsec_process.c: In function ‘ipsec_process’:
../examples/ipsec-secgw/ipsec_process.c:132:34:
error: ‘grp.m’ may be used uninitialized in this function
[-Werror=maybe-uninitialized]
132 | grp[n].cnt = pkts + i - grp[n].m;
| ~~~~~~^~
This is a correct warning for the initial execution of the statement.
However, it is the design of the loop that grp[0].cnt will later be
written with the correct value using an initialized grp[0].m before it
is used.
In order to remove the warning, initialize grp[0].m for the initial and
unused calculation of grp[0].cnt.

library")

v2: just initialize grp[0].m instead of the full array.
note, commit log violates line length but I didn't want to split warning msg.
