[dpdk-dev] [PATCH] devargs: fix freeing during device removal

[Thomas Monjalon]

After calling unplug function of a bus, the device is expected
to be freed. It is too late for getting devargs to remove.
Anyway, the buses which implement unplug are already freeing
the devargs, except the PCI bus.
So the call to rte_devargs_remove() is removed from EAL and
added in PCI.

Fixes: 2effa126fbd8 ("devargs: simplify parameters of removal function")
