[SCSI] mptfusion: Fix Incorrect return value in mptscsih_dev_reset
There's a branch at the end of this function that is supposed to normalize the return value with what the mid-layer expects. In this one case, we get it wrong. Also increase the verbosity of the INFO level printk at the end of mptscsih_abort to include the actual return value and the scmd->serial_number. The reason being success or failure is actually determined by the state of the internal tag list when a TMF is issued, and not the return value of the TMF cmd. The serial_number is also used in this decision, thus it's useful to know for debugging purposes. Cc: stable@kernel.org Reported-by: Peter M.
