ibmvnic: Update driver queues after change in ring size support

[ Upstream commit 5bf032ef08e6a110edc1e3bfb3c66a208fb55125 ]

During device reset, queue memory is not being updated to accommodate
changes in ring buffer sizes supported by backing hardware. Track
any differences in ring buffer sizes following the reset and update
queue memory when possible.
