Subject: [PATCH] eal: fix return codes on thread naming failure

[ upstream commit 82dcc8b4bcb8adcb7fc819839833e74a3d0ad497 ]

The doc says this function returns negative errno
on error, but it currently returns either -1 or
positive errno.

It was incorrectly assumed that pthread_setname_np()
returns negative error numbers. It always returns
positive ones, so this patch negates its return value
before returning.

Fixes: 3901ed99c2f8 ("eal: fix thread naming on FreeBSD")
