alpha: fix floor on sNaN input
The alpha version of floor wrongly return sNaN for sNaN input. Fix that
by checking for NaN and by returning the input value added with itself
in that case.
Finally remove the code to handle inexact exception, floor should never
generate such an exception.
Changelog:
* sysdeps/alpha/fpu/s_floor.c (__floor): Add argument with itself
when it is a NaN.
[_IEEE_FP_INEXACT] Remove.
* sysdeps/alpha/fpu/s_floorf.c (__floorf): Likewise.
