ANDROID: arm64: KVM: Fix missing asm/debug-monitors.h include

This fix is part of upstream commit 03336b1d
("arm64: prevent potential circular header dependencies in asm/bug.h").

That ^^ upstream patch is already backported in common/android-4.4
as Change-Id: I71470b7db9ef858a5a8368a872f931936c723a25
("BACKPORT: arm64: prevent potential circular header dependencies in asm/bug.h")
but it missed this include portion of the patch which bite us back while
backporting arm64-hibernate patches.
