Bart Van Assche 33aea9741e ANDROID: scsi: Retry unaligned zoned writes ...

From ZBC-2: "The device server terminates with CHECK CONDITION status, with
the sense key set to ILLEGAL REQUEST, and the additional sense code set to
UNALIGNED WRITE COMMAND a write command, other than an entire medium write
same command, that specifies: a) the starting LBA in a sequential write
required zone set to a value that is not equal to the write pointer for that
sequential write required zone; or b) an ending LBA that is not equal to the
last logical block within a physical block (see SBC-5)."

I am not aware of any other conditions that may trigger the UNALIGNED
WRITE COMMAND response.

Retry unaligned writes in preparation of removing zone locking.

Increase the number of retries for write commands sent to a sequential
zone to the maximum number of outstanding commands.
