[teamd] fix lacp fallback mode in teamd v1.28 (#3572)

Browse Source 
In teamd v1.28, the port can only be enabled if sync bit is set
in recveived LACPDU from partner by the following commit
"teamd: lacp: update port state according to partner's sync bit"
(54f137c105)

However, lacp fallback feature needs to enable port even if partner
LACPDU is not received within a given period and fallback cfg is enabled.
To fix the lacp fallback breakage, we have to bypass the sync bit
check in lacp fallback mode.
