[klibc] [PATCH] ipconfig: do_pkt_recv() refix ret initialisation

[maximilian attems]

fix:

usr/kinit/ipconfig/main.c: In function ‘ipconfig_main’:
usr/kinit/ipconfig/main.c:350:7: warning: ‘ret’ may be used uninitialized in this function [-Wuninitialized]
usr/kinit/ipconfig/main.c:346:6: note: ‘ret’ was declared here

I think the initialisation change in 6df362216a2e5beb4f29feafeabc630034a76914
was unintentional.

Need to field test it yet, haven't checked it on usage.
