[PATCH 2/2] ctrl_iface: BSS cmd skip mesh scan info if parsing fails

[Jonathan Afek]

In some cases parsing of the mesh scan info for a BSS can
fail. One reason can be that the beacon contained malformed
length vendor IEs which are not parsed when adding to the BSS
table. Instead of skipping the whole BSS of the BSS
command, just skip the mesh scan info.
