[ Upstream commit d3589381987ec879b03f8ce3039df57e87f05901 ]
NVME_REQ_CANCELLED is translated into -EINTR in nvme_submit_sync_cmd(),
so we should be setting this flags during nvme_cancel_request() to
ensure that the callers to nvme_submit_sync_cmd() will get the correct
error code when the controller is reset.

When a command has been aborted we should return NVME_SC_HOST_ABORTED_CMD
to be consistent with the other transports.

[ Upstream commit abbb5f5929ec6c52574c430c5475c158a65c2a8c ]
This adds a quirk for Samsung PM1725a drive which fixes timeouts and
I/O errors due to the fact that the controller does not properly
handle the Write Zeroes command, dmesg log:
