eal: fix bus name read for removal in multi-process

Browse Source 
A crash may appear when removing some PCI devices because
dev->devargs is not always initialized. So use dev->bus instead of
dev->devargs->bus when building devargs string to remove a device.

Fixes: 244d513071 ("eal: enable hotplug on multi-process")
