x86/fpu: Rename init_fpu() to fpu__unlazy_stopped() and add debugging check

This function name is a misnomer now that we've split out all the
other users from it. Rename it accordingly: it's used to save
the FPU state of (ptrace-)stopped child tasks.

Add debugging check to double check this intended usage: that this
function is only called for non-current, stopped child tasks.
