RISC-V: KVM: Fix APLIC in_clrip and clripnum write emulation
In the section "4.7 Precise effects on interrupt-pending bits"
of the RISC-V AIA specification defines that:
"If the source mode is Level1 or Level0 and the interrupt domain
is configured in MSI delivery mode (domaincfg.DM = 1):
The pending bit is cleared whenever the rectified input value is
low, when the interrupt is forwarded by MSI, or by a relevant
write to an in_clrip register or to clripnum."
Update the aplic_write_pending() to match the spec.
Fixes: d8dd9f113e16 ("RISC-V: KVM: Fix APLIC setipnum_le/be write emulation")
