ACPI / PCI: fix acpi_pci_irq_enable() memory leak
[ Upstream commit 29b49958cf73b439b17fa29e9a25210809a6c01c ]
In acpi_pci_irq_enable(), 'entry' is allocated by kzalloc() in
acpi_pci_irq_check_entry() (invoked from acpi_pci_irq_lookup()). However,
it is not deallocated if acpi_pci_irq_valid() returns false, leading to a
memory leak. To fix this issue, free 'entry' before returning 0.
