Avoid setting adapter->num_vfs early in the init code path when using the max_vfs module parameter by passing it to ixgbe_enable_sriov() as a function parameter. This fixes an issue where if we failed to allocate vfinfo in __ixgbe_enable_sriov() the driver will crash with NULL pointer in ixgbe_disable_sriov() when attempting to free the vfinfo struct based on adapter->num_vfs. Also it cleans up the assignment of adapter->num_vfs since now it will only be set in __ixgbe_enable_sriov() and cleared in ixgbe_disable_sriov().
