3.16.82-rc1 review patch. If anyone has any objections, please let me know.

commit 3fe3d2428b62822b7b030577cd612790bdd8c941 upstream.
The variable init_fw_cb is released twice, resulting in a double free bug. The call to the function dma_free_coherent() before goto is removed to get rid of potential double free.
