[PATCH 14/18] conf: Remove redundant warning when SO_BINDTODEVICE is unavailable

[David Gibson <david@gibson.dropbear.id.au>]

conf_ports() has logic to warn if -[TU] auto is specified but we can't use
SO_BINDTODEVICE.  However, this is redundant with similar logic in
conf_ports_range_except().  The latter will be triggered both for an
explicit -[TU] auto and when it's invoked as a default option, so keep that
one and drop the one in conf_ports().
