Borislav Petkov (AMD) 77245f1c3c x86/CPU/AMD: Do not leak quotient data after a division by 0 ...

Under certain circumstances, an integer division by 0 which faults, can
leave stale quotient data from a previous division operation on Zen1
microarchitectures.

Do a dummy division 0/1 before returning from the #DE exception handler
in order to avoid any leaks of potentially sensitive data.
