[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.
