The comment for sta_info_flush() states
"Returns the number of removed STA entries"
but that isn't actually true. Consequently,
the warning when a station is still around
on interface removal can never trigger and
this delayed finding the timer issue the
previous patch fixed. Fix the return value
here to make that warning useful again.

When removing an interface while it is in the
process of authenticating or associating, we
leak the auth_data or assoc_data, and leave
the timer pending. The timer then crashes the
system when it fires as its data is gone.

Fix this by explicitly deleting all the data
when the interface is removed. This uncovered
another bug -- this problem should have been
detected by the sta_info_flush() warning but
that function doesn't ever return non-zero,
I'll fix that in a separate patch.
