[SCSI] sg: fix incorrect page problem
There's a problem where sg is executing a ->nopage operation on a compound page, it actually calls get_page() on the first page in the compound rather than the page which is being mapped. The fix is to select the correct page by indexing into the compound. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
