Yang Yingliang 61263b3a11 scsi: elx: efct: Don't use GFP_KERNEL under spin lock 
GFP_KERNEL/GFP_DMA can't be used under a spin lock. According the comment,
els_ios_lock is used to protect els ios list so we can move down the spin
lock to avoid using this flag under the lock.

dma_alloc_coherent() ignores the zone specifiers so this is pointless and
confusing.
