We should return -ENOMEM in case of memory allocation error, as done
elsewhere in this function.

We need to add a bus reset no-op as without it some of the LUNs attached to a
vport may go offline when the error handler escalates to host reset due to not
having a bus reset handler in the driver. What happens is we escalate to host
reset which does a soft link down/link up to reset the adapter. However with
multiple vports attached it's been observed that if the vports do log back into
the target within 5 seconds, the SCSI layer offlines the devices most likely
due to a TUR timing out to verify that the device is online. Adding a bus
reset handler will cause the TUR to be sent after the bus reset handler where
the devices will still be online if the bus reset is initiated by sg_reset
(which is the case in the test that was failing). The bus reset will succeed
and not needlessly bring the device offline/online.

We should be using the same logic to do a soft reset of the FCoE function
whether it is initiated via sg_reset or the fc_host issue_lip attribute.
Refactor the host reset and fcoe reset handlers to use the preferred logic
which is currently contained in qedf_eh_host_reset().

For libfc to register FDMI attributes we need to do two things:
- Set the appropriate fc_host attributes that libfc will use to form the
FDMI registration commands
- Set lport->fdmi_enabled to 1

Using memcpy() from a string that is shorter than the length copied
means the destination buffer is being filled with arbitrary data from
the kernel rodata segment. Instead, use strncpy() which will fill the
trailing bytes with zeros.
This was found with the future CONFIG_FORTIFY_SOURCE feature.
