Subject: [PATCH 2/2] Do not set shared_ports when nreq > MAX_MSIX

From: Carol L Soto <clsoto@...ux.vnet.ibm.com>

If we get MAX_MSIX interrupts would like to have each receive ring
with his own msix interrupt line.

Fixes: 9293267a3e2a ('net/mlx4_core: Capping number of requested MSIXs to MAX_MSIX')
