I wander how we can skip sbc_dif_verify_ if the transport already

When an MBX command timeout happens,the resources associated with
the MBX command were freed. If FW were to give the response to
host after the timeout value set by driver then driver crashes as the MBX Cmd
resources were already freed.
This patch fixes this issue by maintaing a state flag
The 100Mbps port speed macro used was not proper.
