PCI: Handle FLR failure and allow other reset types
pci_flr_wait() and pci_af_flr() functions assume graceful return even
though the device is inaccessible under error conditions.
Return -ENOTTY in error cases so that __pci_reset_function_locked() can
try other reset types if AF_FLR/FLR reset fails.
