ice: Fix bad register reads

ice: Fix bad register reads

The "ethtool -d" handler reads registers in the ice_regs_dump_list array
and returns read values back to the userspace.

The register offsets PFINT0_ITR* are not valid as per the specification
and reading these causes a "unable to handle kernel paging request" bug
in the driver. Remove these registers from ice_regs_dump_list.
