You want:

update reply {
	&DHCP-Vendor = "%{bin:%{redis: GET %{control:Pool-Name}:option}}"

Bin takes a hex string and returns a buffer containing the binary data.  Bin doesn't require a 0x prefix, but will automatically strip one if it finds one.

It's a bit annoying needing to jump through these hoops though.  I'm guessing you're inserting the hexits into redis instead of the binary string?  The xlat is binary safe so you shouldn't need to do that...
