[PATCH 2/3] virtiofsd: check whether lo_map_reserve returns NULL in, main func

In main func, func lo_map_reserve is called without NULL check. If reallocing new_elems fails in func lo_map_grow, the func lo_map_reserve may return NULL. We should check whether lo_map_reserve returns NULL before using it. Signed-off-by: Haotian Li Signed-off-by: Zhiqiang Liu --- tools
