Thumb-2: Correctly handle undefined instructions in the kernel

VFP instructions in the kernel may trigger undefined exceptions if VFP
hardware is not present. This patch corrects the loading of such Thumb-2
instructions. It also marks the "no_fp" label as a function so that the
linker generate a Thumb address.
