Subject: gve: Update mgmt_msix_idx if num_ntfy changes
Patch-mainline: v5.13-rc4
Git-commit: e96b491a0ffa35a8a9607c193fa4d894ca9fb32f
References: bsc#1176940

If we do not get the expected number of vectors from
pci_enable_msix_range, we update priv->num_ntfy_blks but not
priv->mgmt_msix_idx. This patch fixes this so that priv->mgmt_msix_idx
is updated accordingly.

Fixes: f5cedc84a30d ("gve: Add transmit and receive support")
