[PATCH] dma/skeleton: fix pthread set affinity

In skeleton dma driver, the user can pin the dma thread to desired
cpu core. The previous commit changed the api from set-affinity to
get-affinity leading to thread to be pinned to first available lcore.

Bugzilla ID: 1270
Fixes: 7fdf30d8b259 ("eal/windows: remove most pthread lifetime shim functions")
