Do not consider the fixed size of hv_vp_set when passing the variable
header size to hv_do_rep_hypercall().
The Hyper-V hypervisor specification states that for a hypercall with a
variable header only the size of the variable portion should be supplied
via the input control.
For HVCALL_FLUSH_VIRTUAL_ADDRESS_SPACE_EX/LIST_EX calls that means the
fixed portion of hv_vp_set should not be considered.
That fixes random failures of some applications that are unexpectedly
killed with SIGBUS or SIGSEGV.
