Remove <object> cast in real_mpfi.pyx

[jdemeyer]

The following is very wrong code (from sage/rings/real_mpfi.pyx)

# todo: The <object> coerce is evidently to get around a weird bug in SageX (?)   
mpfi_interv_q(self.value, <object>rat.value, <object>rat1.value) 

Surprisingly, it only breaks on PPC64. See #11705 for more context.

Component: porting
