If hif_read_reg() or hif_write_reg() fail in wilc_wlan_cleanup(),
it calls release_bus() and continues execution. But it leads to double
release_bus() call that means double unlock of g_linux_wlan->hif_cs mutex.

If hif_read_reg() or hif_write_reg() fail in wilc_wlan_cleanup(),
it calls release_bus() and continues execution. But it leads to double
release_bus() call that means double unlock of g_linux_wlan->hif_cs mutex.
The patch adds return in case of failure.
