Subject: [PATCH 1/2] usb: gadget: mv_u3d_core: Correct clk_disable twice

There is a call to clk_disable a few lines before the goto
err_alloc_ep_context. The clk goes not get enabled anywhere after that
so this is not required. This patch fixes the bug by removing the deinit
and clk_disable after the goto statement.
