rtlwifi: fix incorrect use of usb_alloc_coherent with usb_control_msg

Incorrect use of usb_alloc_coherent memory as input buffer to usb_control_msg
can cause problems in arch DMA code, for example kernel BUG at
'arch/arm/include/asm/dma-mapping.h:321' on ARM (linux-3.4).

Change _usb_writeN_sync use kmalloc'd buffer instead.
