At ieee80211_join_mesh() some ie data could have been allocated (see
copy_mesh_setup()) and need to be cleaned up when leaving the mesh.
This fixes the following kmemleak report:
unreferenced object 0xffff0000116bc600 (size 128):
comm "wpa_supplicant", pid 608, jiffies 4294898983 (age 293.484s)
hex dump (first 32 bytes):
