qcacld-3.0: Release the PDEV ref count by adding a new goto label

The function hdd_rx_mic_error_ind() is not releasing the pdev reference,
causing a pdev object manager leak for the WMI command WLAN_MLME_SB_ID.
To solve this, add a new goto label release_ref_and_return that releases
the pdev ref count before exiting the function.
