As per IEEE 802.11be-2024 - 9.4.2.321, EHT operation element
contains MCS15 Disable subfield as the sixth bit, which is set when
MCS15 support is not enabled.
Get MCS15 support from EHT operation params and add it in link_conf
so that driver can use this value to know if EHT-MCS 15 reception
is enabled.
