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.
