[VLAN]: Fix SET_VLAN_INGRESS_PRIORITY_CMD ioctl

Based on report and patch by Doug Kehn <rdkehn@yahoo.com>:

vconfig returns the following error when attempting to execute the
set_ingress_map command:

vconfig: socket or ioctl error for set_ingress_map: Operation not permitted

In vlan.c, vlan_ioctl_handler for SET_VLAN_INGRESS_PRIORITY_CMD
sets err = -EPERM and calls vlan_dev_set_ingress_priority.
vlan_dev_set_ingress_priority is a void function so err remains
at -EPERM and results in the vconfig error (even though the ingress
map was set).

Fix by setting err = 0 after the vlan_dev_set_ingress_priority call.
