netdev-vport: Don't use ipsec options for either arg in config_equal_ipsec().

netdev-vport: Don't use ipsec options for either arg in config_equal_ipsec().

Commit aebf423 (netdev: Add methods to do netdev-specific argument
comparisons.) added a new config_equal_ipsec() function to ignore
IPsec key options when comparing an existing netdev's options with a new
netdev.  We only ignored the options for the new netdev configuration,
which works when pulling the existing configuration from the kernel.
Unfortunately, if this is just a re-init of a netdev for which we just
created, this ignoring of the IPsec key options on the new netdev will
cause the check to fail, since the full options actually available in
both netdevs.  This commit just ignore all IPsec key options from both
netdevs.
