qcacld-3.0: Use link info to fetch BW and oper channel APIs

The BW and operating channel will be present in each link's session.
Refactor the below two APIs to take link info as function argument
instead of adapter to get each link's data.

The following APIs are renameed and existing callers moved to deflink.
1) hdd_get_adapter_width() => hdd_get_link_info_width()
2) hdd_get_adapter_home_channel() => hdd_get_link_info_home_channel()
