[SCSI] megaraid_sas: FW transition and q size changes
This patch has the following enhancements :
a. handles new transition states of FW to support controller hotplug.
b. It reduces by 1 the maximum cmds that the driver may send to FW.
c. Sends "Stop Processing" cmd to FW before returning failure from reset routine
d. Adds print in megasas_transition routine
e. Sends "RESET" flag to FW to do a soft reset of controller
to move from Operational to Ready state.
f. Sending correct pointer (cmd->sense) to pci_pool_free
