qcacld-3.0: Remove hdd_update_eht_cap_in_cfg() prototype

A prototype for hdd_update_eht_cap_in_cfg() was added as part of:
  qcacld-3.0: Add APIs to update 11be target capabilities
  Change-Id Ib3baa41ea3d8ef2ce49b88e4b48d8bc29556cd66

But no actual function was added, so remove the unused prototype.
