x86/fpu: Rename copy_user_to_xregs() and copy_xregs_to_user()
The function names for xsave[s]/xrstor[s] operations are horribly named and
a permanent source of confusion.
Rename:
copy_xregs_to_user() to xsave_to_user_sigframe()
copy_user_to_xregs() to xrstor_from_user_sigframe()
so it's entirely clear what this is about. This is also a clear indicator
of the potentially different storage format because this is user ABI and
cannot use compacted format.
No functional change.
