Subject: [PATCH] pdump: fix error check when creating/canceling thread

[ upstream commit 2969258cb41064d2295ac823f385ad41ef405f15 ]

On error, pthread_create() returns a positive number (an errno)
but does not set the errno variable.

Fixes: 278f945402c5 ("pdump: add new library for packet capture")
