  ethdev requires device to be configured before setting MTU.

In bonding PMD, while configuring slaves, bonding first sets MTU later
configures them, which causes failure if slaves are not configured in
advance.

Fixing by changing the order in slave configure as requested in ethdev
layer, configure first and set MTU later.
