[PATCH] dns: remove redundant zero length namelen check

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The zero namelen check is redundant as it has already been checked
for zero at the start of the function.  Remove the redundant check.

Addresses-Coverity: ("Logically Dead Code")
