[PATCH 2/2] fusion : VMWare guest OS remounted as read only fix

[Eric Moore <eric.moore@lsi.com>]

This address the issue of VMWare guest OS being remounted as read-only becuase the underlying device was held busy too long, , and at the same time address Engenio MPP driver concerns over infinite retries.  This patch removes the code that snoops the SAM STATUS on busy, which would be returning DID_BUS_BUSY, instead we return the status as is.   Retry hanlding seems to be properly handled in scsi_softirq_done, where a busy sam status would only occurr for the time specified by (cmd->allowed  +1) * cmd->timeout_per_command.
