[U-Boot] [PATCH 2/3] usb:gadget:Remove redundant #includes for USB composite gadget and its functions

[Lukasz Majewski]

Only the <linux/usb/gadget.h> requires error.h include. Hence, several
includes of error.h at USB gadget functions are not needed.

Moreover unnecessary malloc.h includes were also removed.
