ACPI, PCI, irq: remove redundant check for null string pointer
source is decleared as a 4 byte char array in struct acpi_pci_routing_table
so !prt->source is a redundant null string pointer check. Detected with
smatch:
drivers/acpi/pci_irq.c:134 do_prt_fixups() warn: this array is probably
non-NULL. 'prt->source'
