qcacld-3.0: Fix sme_get_bss_transition_status() signature

The signature for sme_get_bss_transition_status() indicates it returns
an int errno, and that is what the only caller is currently expecting,
but in reality it returns QDF_STATUS. Since SME APIs are generally
expected to return QDF_STATUS, update the signature as well as the
caller to use QDF_STATUS.
