Log Message:

Fix KASSERT failure with floating-point exception in userland.

Consider the case in which curlwp owns enabled FPU in vfp_handler().
If FPE is raised, we must skip pcu_load(9) rather than just falling
through. Otherwise, KASSERT fires in vfp_state_load(), since curlwp
already owns enabled FPU.

No regression for ATF is introduced.
