qcacld-3.0: Return error status to user space if set fast roam fails

Currently, when the set fast roam from user space fails in HDD, host
driver is not returning failure status. This causes timeout in user
space awaiting more data from driver eventually leading to supplicant
driver connection loss and wifi disabling and re-enabling.

Return failure status when the set fast roam command fails in HDD.
