pc64: fix fpu bug
fpurestore() unconditionally changed fpstate to FPinactive when
the kernel used the FPU. but in the FPinit case, the registers are
not saved by mathemu(), resulting in all zero initialized registers
being loaded once userspace uses the FPU so the process would have
wrong MXCR value.
the index overflow check was wrong with using shifted value.
