[PATCH v3 1/2] eal: fix off by one in in tailq name init

[Stephen Hemminger <stephen@networkplumber.org>]

The tailq name is defined as 32 bytes, but name would be
silently truncated at 31 bytes. The function strlcpy() size
already accounts for the nul character at the end.


Fixes: f9acaf84e923 ("replace snprintf with strlcpy without adding extra include")
