hv: rename vlapic_pir_desc to pi_desc

Browse Source 
Rename struct vlapic_pir_desc to pi_desc
Rename struct member and local variable pir_desc to pid

pir=posted interrupt request, pi=posted interrupt
pid=posted interrupt descriptor
pir is part of pi descriptor, so it is better to use pi instead of pir

struct pi_desc will be moved to vmx.h in subsequent commit.
