eal: fix deadlock in hot-unplug

When device be hot-unplugged, the hot-unplug handler will be invoked by uio
remove event and the device will be detached, then kernel will sent another
pci remove event. So if there is any unlock miss, it will cause a dead lock
issue. This patch will add this missing unlock for hot-unplug handler.

Fixes: 0fc54536b14a ("eal: add failure handling for hot-unplug")
