[SCSI] sd: update index allocation and use ida instead of idr
Update index allocation as follows. * sd_index_idr is used only for ID allocation and mapping functionality is not used. Use more memory efficient ida instead. * idr and ida have their own locks inside them and don't need them for operation. Drop it. * index wasn't freed if probing failed after index allocation. fix it. * ida allocation should be repeated if it fails with -EAGAIN.
