SoftApManager: Set country code before channel selection
If the country code is not set for some reason previously
(For example: STA was off when telephony sent the country
code update), we should first set the country code before
performing channel selection for AP.
Also, added an extra error check for country code when the band
selected is 5Ghz.
Bug: 111135704
Test: Unit tests
Test: Able to toggle hotspot on/off.
Test: Ran SoftapManager ACTS tests locally.
