[PATCH] Fix Trivial Warnining in drivers/ata/libata-scsi.c

[Subrata Modak <subrata@linux.vnet.ibm.com>]

Hi Jeff,

I observed the following warning for drivers/ata/libata-scsi.c:

drivers/ata/libata-scsi.c: In function ‘ata_scsi_scan_host’:
drivers/ata/libata-scsi.c:3272: warning: ‘dev’ may be used uninitialized in this function
---

In most instances=>
	struct ata_device *dev
has been initialized except the above instance. My trivial patch below fixes this.
Please include it if you like it.
