Ethan Tidmore b5f50519bf x86/hyperv: Fix error pointer dereference ...

[ Upstream commit 705d01c8d7 ]

The function idle_thread_get() can return an error pointer and is not
checked for it. Add check for error pointer.

Detected by Smatch:
arch/x86/hyperv/hv_vtl.c:126 hv_vtl_bringup_vcpu() error:
'idle' dereferencing possible ERR_PTR()
