error recovery timeout is dictated from the nvme

PTR_ERR should be applied before its argument is reassigned, otherwise the
return value will be set to 0, not error code.

This patch implements the RDMA host (initiator in SCSI speak) driver. It
can be used to connect to remote NVMe over Fabrics controllers over
Infiniband, RoCE or iWarp, and uses the existing NVMe core driver as well
a the new fabrics library.
To connect to all NVMe over Fabrics controller reachable on a given taget
port using RDMA/CM use the following command:
nvme connect-all -t rdma -a $IPADDR
This requires the latest version of nvme-cli with Fabrics support.
