PCI: Omit PCI ID macro strings to shorten quirk names

Pasting the verbatim PCI_(VENDOR|DEVICE)_* macros in the __pci_fixup_*
symbol names results in insanely long names such as

__pci_fixup_resumePCI_VENDOR_ID_SERVERWORKSPCI_DEVICE_ID_SERVERWORKS_HT1000SBquirk_disable_broadcom_boot_interrupt

When Link-Time Optimization adds its numeric suffix to such symbol, it
overflows the namebuf[KSYM_NAME_LEN] array in kernel/kallsyms.c.  Use the
line number instead to create (nearly) unique symbol names.
