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.
