Subject: [PATCH] ibmvnic: Allocate max queues stats buffers

References: bsc#1081498
Patch-mainline: v4.17-rc1
Git-commit: abcae546f7b49f02f4b73d6cc8b33c2fc5f2f8a4

To avoid losing any stats when the number of sub-crqs change, allocate
the max number of stats buffers so a stats buffer exists all possible
sub-crqs.
