sparc32, copy_thread: Clear TIF_USEDFPU flag of created task instead of current

FPU state is saved into task_struct of created task. Current task continues
use of the state, so it needs TIF_USEDFPU flag is not cleared.

Created task receives fresh FPU and cleared TIF_USEFPU flag is required for it.
