[patch 1/6] zfcp: Remove unnecessary eh_bus_reset_handler callback

[swen@vnet.ibm.com]

[-- Attachment #1: 800-zfcp-callback.diff --]
[-- Type: text/plain, Size: 1703 bytes --]

From: Christof Schmitt <christof.schmitt@de.ibm.com>

The callback function used by zfcp always returns success,
which is an indication for the SCSI midlayer to stop error
handling. Remove the bus_reset callback, since the same
function will be called via the host_reset callback.
