[patch] scsi/initio: add GFP_KERNEL flag

[Dan Carpenter <error27@gmail.com>]

Calling scb = kzalloc(i, GFP_DMA) is not the right idea.  If this is
what we really wanted it would be better to specify it explicitly as 
kzalloc(i, GFP_NOWAIT | GFP_DMA).  But in this case it's OK to wait so
I changed it to use GFP_KERNEL.  Also I added a __GFP_NOWARN, since we
expect the allocation to fail occasionaly (and we just try allocate a 
smaller amount on the next time through the loop).
