Subject: vxlan: Update vxlan fdb 'used' field after each usage
From: Sridhar Samudrala <sri@xxxxxxxxxx>
[ Upstream commit 014be2c8eac3381e202f684c1f35ae184a8b152b ]
Fix some instances where vxlan fdb 'used' field is not updated after the entry
is used.
v2: rename vxlan_find_mac() as __vxlan_find_mac() and create a new vxlan_find_mac()
that also updates ->used field.
