Fix test_hotspot_upstream_wifi not running consistently

The isStaApConcurrencySupported() returns Unit instead of a
boolean value, which is interpreted as a falsy value when called
from the host in Python. This will cause the Wi-Fi AP + STA
concurrency check to always be skipped and preventing the
test_hotspot_upstream_wifi test from running. This incorrect
logic should be fixed to ensure it accurately reflects the
device's capabilities.

Test: atest CtsConnectivityMultiDevicesTestCases
