Subject: [PATCH net] intersil/hostap: Fix outdated comment about dev->destructor

After commit cf124db566e6 ("net: Fix inconsistent teardown and
release of private netdev state."), setting
'dev->needs_free_netdev' ensures device data is released, and
'dev->destructor' is not used anymore.

Fixes: cf124db566e6 ("net: Fix inconsistent teardown and release of private netdev state.")
Signed-off-by: Stefano Brivio <sbrivio@...hat.com>

Despite checkpatch.pl warning against unnecessary changes, this
outdated comment might lead to confusion -- making this change
actually necessary, perhaps.
