Subject: [PATCH 24/24] misc: pci_endpoint_test: Fix test_reg_bar to be updated in pci_endpoint_test

commit 834b9051992580ac8fd3966d023b ("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. This results in
test_reg_bar having invalid value when used outside probe. Fix it here.

Fixes: 834b9051992580ac8fd3966d023b ("misc: pci_endpoint_test: Add support
for PCI_ENDPOINT_TEST regs to be mapped to any BAR")
