Currently, there is no book keeping of the pending scsi commands in =
the
cxlflash driver. This lack of tracking in-flight requests is too
restrictive and requires a heavy-hammer reset each time an adapter =
error is
encountered. Additionally, it does not allow for commands to be =
properly
retried.

In order to avoid this problem and to better handle error path command
cleanup, introduce a linked list for each hardware queue that tracks
pending commands.
