x86/xen: Fix memory leak in xen_smp_intr_init{_pv}()
[ Upstream commit 69143f60868b3939ddc89289b29db593b647295e ]
These local variables @{resched|pmu|callfunc...}_name saves the new
string allocated by kasprintf(), and when bind_{v}ipi_to_irqhandler()
fails, it goes to the @fail tag, and calls xen_smp_intr_free{_pv}() to
free resource, however the new string is not saved, which cause a memory
leak issue. fix it.
