Revert de3171043b3cbe078e410351a00e5756509bd514 and
some of 537d67b19a4b72d72341e529f611e4e30754f8fc

In osm_mcast_tbl_realloc, don't change max_mlid_ho when mlid_offset < 
p_tbl->mft_depth
Also, restore some checks when mlid_offset >= p_tbl->mft_depth
These changes are needed for proper group removal
