[PATCH v5] cifs: Allocate validate negotiation request through kmalloc

From: Long Li The data buffer allocated on the stack can't be DMA'ed, ib_dma_map_page will return an invalid DMA address for a buffer on stack. Even worse, this incorrect address can't be detected by ib_dma_mapping_error. Sending data from this address to hardware will not
