[PATCH -next] scsi: initio: Fix missing memory allocation modifier

[Yang Li]

The function initio_probe_one() allocates a DMA buffer without the
GFP_KERNEL modifier, fix this by using (GFP_KERNEL | GFP_DMA) instead of
only GFP_DMA as the probe happens in non-interrupt context.

At the same time, change the if statement to the more typical kernel
style.

Eliminate the follow smatch warning:
drivers/scsi/initio.c:2850 initio_probe_one() error: no modifiers for
allocation.
