    Remove incorrect register mov in floorf/nearbyint on x86_64
    
    The change in 0b5395f052ee09cd7e3d219af4e805c38058afb5 replaced calls
    to __get_cpu_features@plt followed by a mov from rax to rdx, with a
    single macro LOAD_RTLD_GLOBAL_RO_RDX.  It is pretty clear that there
    was a typo in s_floorf and __nearbyint due to which the (now incorrect)
    mov was not removed.  This patch removes that mov.
    
        * sysdeps/x86_64/fpu/multiarch/s_floorf.S (__floorf): Remove
        unnecessary movq.
        * sysdeps/x86_64/fpu/multiarch/s_nearbyint.S (__nearbyint):
        Likewise.
