fix clib_mem_unaligned() invalid read
clib_mem_unaligned + zap64 casts its input as u64, computes a mask according to the input length, and returns the casted maked value. Therefore all the 8 Bytes of the u64 are systematically read, and the invalid ones are discarded. For example, for a 5-Bytes string, we will do an invalid read of size 3, even though those 3 Bytes are never used. This patch proposes to only read what we have at the cost of reading as a u64 in one call, but that way, we do not trigger an invalid read error.
