ibmvnic: Allocate number of rx/tx buffers agreed on by firmware

[ Upstream commit 068d9f90a6978c3e3a662d9e85204a7d6be240d2 ]

The amount of TX/RX buffers that the vNIC driver currently allocates
is different from the amount agreed upon in negotiation with firmware.
Correct that by allocating the requested number of buffers confirmed
by firmware.
