vfio/listener: Remove unnecessary 'linux/kvm.h' include

Since commit d0e8bccafc23 ("hw/vfio/listener.c: remove CONFIG_KVM"), the linux/kvm.h include is unconditional. This breaks the build on targets that lack asm/kvm.h such as sparc and sparc64: In file included from ../hw/vfio/listener.c:23: linux-headers/linux/kvm.h:16:10: fatal error: asm/kvm.h: No such file or directory This include is not needed in listener.c which only uses kvm_enabled() and kvm_get_max_memslots(), both are declared in "system/kvm.h". Remove it.
