[PATCH] lib/genaloc: Fix allocation of aligned buffer from non-aligned chunk

On success, gen_pool_first_fit_align() returns the bit number such that chunk_start_addr + (bit << order) is properly aligned. On failure, the bitmap size parameter is returned. When the chunk_start_addr isn't aligned properly, the chunk_start_addr + (bit << order) isn't aligned too. To fix
