Rafael Mendonca bff553de2c virtio_blk: Fix signedness bug in virtblk_prep_rq()
[ Upstream commit a26116c1e74028914f281851488546c91cbae57d ]

The virtblk_map_data() function returns negative error codes, however, the
'nents' field of vbr->sg_table is an unsigned int, which causes the error
handling not to work correctly.
