qcacld-3.0: refactor hdd_wlan_get_version to be adapter independent

hdd_wlan_get_version is invoked with adapter as a parameter, internally
in the function it is used to extract the hdd context.

Directly pass the hdd context to hdd_wlan_get_version so that it shall
be adapter agnostic and clean up the local variables for the camelcase
and hungarian notion.
