The hypervisor copies of the SVE save and load functions are prototyped
with third arguments specifying FFR should be accessed but the assembly
functions overwrite whatever is supplied to unconditionally access FFR.
Remove this and use the supplied parameter.

This has no effect currently since FFR is always present for SVE but will
be important for SME.
