x86/hyperv: drop all __packed from hyperv-tlfs.h
All structures are already naturally aligned. Linux added those
attributes out of paranoia.
In Xen we've had instance we had to drop pointless __packed to placate
gcc 9 (see ca9310b24e "x86/IO-APIC: fix build with gcc9"), it is better
to drop those attributes in hyperv-tlfs.h as well.
