[PATCH] ctrl_iface: Don't return -1 when dumping BSS information

[Andrei Otcheretianski]

From: Johannes Berg <johannes.berg at intel.com>

Don't ever return -1 from print_bss_info() as that causes
corruption of the output.

Also don't return -1 from print_fils_indication() as that
would stop the iteration over all BSSs.
