iwlwifi: yoyo: don't add TLV offset when reading FIFOs

The TLV offset is only used to read registers, while the offset used for
the FIFO addresses are hard coded in the driver and not given by the
TLV.

If we try to apply the TLV offset when reading the FIFOs, we'll read
from invalid addresses, causing the driver to hang.
