qcacld-3.0: Update max he mcs index correctly

Currently driver does not consider kernel version
when it updates max he mcs index, kernel version
prior to 5.4 supports max he index as 11 and while
5.4 kernel version onwards max he index 14 is
supported. In current implementation driver might
update max he index more than 11 for kernel version
less than 5.4 also which is an invalid value for kernel
version less than 5.4.

To address above issue update correct max he mcs index based
on kernel version.
