[ Upstream commit 8f220664570e755946db1282f48e07f26e1f2cb4 ]

commit 834b90519925 ("misc: pci_endpoint_test: Add support for
PCI_ENDPOINT_TEST regs to be mapped to any BAR") while adding
test_reg_bar in order to map PCI_ENDPOINT_TEST regs to be mapped to any
BAR failed to update test_reg_bar in pci_endpoint_test, resulting in
test_reg_bar having invalid value when used outside probe.

Fix it.
