[PATCH] nvme: reset retires after path failover

Gah, please ignore this one. I tested on the wrong device.

But FYI, when triggering a path failure in my RDMA setup (setting one
switch port down) I get these nice messages:
[ 1148.124063] nvme nvme0: SEND for CQE 0xffff8817c3720180 failed with
status transport retry counter exceeded (12)
[ 1148.180489] nvme nvme0: failed nvme_keep_alive_end_io error=10
[ 1148.187887] nvme nvme0: Reconnecting in 10 seconds...
[ 1148.194356] print_req_error: I/O error, dev nvme0n1, sector 1690128
[ 1148.194361] print_req_error: I/O error, dev nvme0n1, sector 1692168
[ 1148.194367] print_req_error: I/O error, dev nvme0n1, sector 1694208
[ 1148.379058] XFS (nvms0n1): writeback error on sector 1628688

the nvme ones are expected, but I don't really like to see writeback
errors from the FS here. Something's still a bit off.

Byte,
        Johannes
