 Log Message:
 PR port-arm/55790
 
 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.
