qcacld-3.0: Don't modify BTM capability in the extended capabilities

Browse source 
Currently the host driver checks if the BTM offload is enabled
via ini configuration and sets the BTM enabled bit of the
extended capabilities if BTM offload is enabled. The supplicant
decides if BTM is needed to be enabled or disabled based on the
PMF capability of the AP, since the STA is MBO certified.

When driver sets the BTM capability based on the btm_offload ini,
even if the AP supports MBO and doesn't advertise PMF, BTM is
honored by the MBO certified STA. This violates the MBO spec
that PMF is mandatory for MBO. So with the BTM capability
controlled by userspace, the BTM capability will be advertised
to MBO AP only if PMF is advertised as required for that AP.

Don't modify the BTM capability, and advertise it as it is
provided by the userspace. Firmware will drop the packet if
BTM capability is not advertised during initial connection.
