From: Eric Biggers <[email protected]> Due to a bad merge resolution between commit f29810335965 ("KVM/x86: Check input paging mode when cs.l is set") and commit b4ef9d4e8cb8 ("KVM: Move vcpu_load to arch-specific kvm_arch_vcpu_ioctl_set_sregs"), there is a case in kvm_arch_vcpu_ioctl_set_sregs() where vcpu_put() is not called after vcpu_get(). Fix it.
