qcacld-3.0: Disable legacy netdev params for TDLS

Since TDLS and STA share a common netdev interface,
when STA connection is made in 11a, 11b, 11g mode,
netdev parameters such as TSO/checksum are disabled.
If TDLS connection is formed over this Station,
TSO remains disabled as STA netdev is used.

This might result in loss of throughput when TDLS
connection is made with 11n, 11ac, 11ax dot11mode and
with wider bandwidth TDLS, this loss is more prominent.

Hence, overwrite the netdev params to enable TSO when
TDLS connection is formed in 11ax, 11ac, 11n mode if
the station is in 11a, 11b, 11g mode.
Also, disable the TSO params when TDLS tearsdown when
STA is in 11a, 11b, 11g mode.
