selftests: pci_endpoint: Skip BAR subrange test on -ENOSPC
In pci-epf-test.c, set the STATUS_NO_RESOURCE status bit if
pci_epc_set_bar() returns -ENOSPC. This status bit is used to indicate
that there are not enough inbound window resources to allocate the
subrange.
In pci_endpoint_test.c, return -ENOSPC instead of -EIO when
STATUS_NO_RESOURCE is set.
In pci_endpoint_test.c, skip the BAR subrange test if -ENOSPC, i.e., there
are not enough inbound window resources to run the test.
