Some gcc versions don't seem to be able to properly track the flow of
the smp_cmd_pairing_random() function and end up causing the following
types of (false-positive) warnings:
smp.c:1995:6: warning: ‘nb’ may be used uninitialized in this function [-Wmaybe-uninitialized]
err = smp_g2(smp->tfm_cmac, pkax, pkbx, na, nb, &passkey);
smp.c:1995:6: warning: ‘na’ may be used uninitialized in this function [-Wmaybe-uninitialized]
err = smp_g2(smp->tfm_cmac, pkax, pkbx, na, nb, &passkey);
^
smp.c:1995:6: warning: ‘pkbx’ may be used uninitialized in this function [-Wmaybe-uninitialized]
err = smp_g2(smp->tfm_cmac, pkax, pkbx, na, nb, &passkey);
^
smp.c:1995:6: warning: ‘pkax’ may be used uninitialized in this function [-Wmaybe-uninitialized]
err = smp_g2(smp->tfm_cmac, pkax, pkbx, na, nb, &passkey);
This patch fixes the issue by moving the pkax/pkbx and na/nb
initialization earlier in the function.
