arm/arm64: KVM: Fix set_clear_sgi_pend_reg offset
commit 0fea6d76 upstream. The sgi values calculated in read_set_clear_sgi_pend_reg() and write_set_clear_sgi_pend_reg() were horribly incorrectly multiplied by 4 with catastrophic results in that subfunctions ended up overwriting memory not allocated for the expected purpose. This showed up as bugs in kfree() and the kernel complaining a lot of you turn on memory debugging.
