x86, fpu: remove unnecessary user_fpu_end() in save_xstate_sig()

Browse source

Few lines below we do drop_fpu() which is more safer. Remove the
unnecessary user_fpu_end() in save_xstate_sig(), which allows
the drop_fpu() to ignore any pending exceptions from the user-space
and drop the current fpu.
