misc: pci_endpoint_test: Validate BAR index in doorbell test
pci_endpoint_test_doorbell() reads the BAR number directly from an endpoint
test register and uses it as an index into test->bar[]. Add a defensive
bounds check before the dereference: positive values >= PCI_STD_NUM_BARS
are out of range, and NO_BAR (-1) as a negative signed value would slip
past an upper-bound-only check.
