ANDROID: scsi: core: Limit zoned write retries

Decrement the command retry counter before retrying a zoned write.

This patch has not been posted on any Linux kernel mailing list since
there is agreement that another approach will be taken to preserve the
order of WRITE commands for zoned devices. However, the implementation
of that new approach is not yet available.
