qcacld-3.0: Fix memory leak in sme_get_link_speed

In the API sme_get_link_speed, the driver allocates memory
to the req, needed to get link speed from firmware
but is not freed, thus a memory leak may happen.

Fix is to remove the req from this API as the driver already
has this info from caller API.
