Subject: ACPI / PCI: Fix memory leak in acpi_pci_irq_enable()
commit b685f3b1744061aa9ad822548ba9c674de5be7c6 upstream.
acpi_pci_link_allocate_irq() can return negative gsi even if
entry != NULL. For that case we have a memory leak, so free
entry before returning from acpi_pci_irq_enable() for gsi < 0.
