qcacld-3.0: Refactor hdd_get_max_tx_bitrate() API

To maintain the stats of each link, hdd_stats is moved
to per link data structure. To update the Tx parameters
for a specific link, change the hdd_get_max_tx_bitrate()
API function argument to take link info pointer.
Existing callers moved to deflink.
