[SCSI] libosd: osd_req_{read,write}_kern new API
By popular demand, define usefull wrappers for osd_req_read/write that recieve kernel pointers. All users had their own. Also remove these from exofs Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
