hwmon: (aquacomputer_d5next) Fix length of speed_input array

Commit 120584c ("hwmon: (aquacomputer_d5next) Add support for Octo
flow sensor") added support for reading Octo flow sensor, but didn't
update the priv->speed_input array length. Since Octo has 8 fans, with
the addition of the flow sensor the proper length for speed_input is 9.

Reported by Arne Schwabe on Github [1], who received a UBSAN warning.
