bgpd:Fixing the signature of community_free function

Browse Source 
community_free, lcommunity_free and ecommunity_free are similar type of functions. Most of the places, these three are called together. The signature of community_free is different from other two functions. Modified the community_free API signature to align with other two functions to avoid any confusion. There is no functionality impact with this and this is just to avoid any confusion.

Testing: manual testing and show commands
