scsi: message: fusion: Correct definitions for mptscsih_dev_reset()

Browse source 
mptscsih_dev_reset() is _not_ a device reset, but rather a target
reset. Nevertheless it's being used for either purpose.  This patch adds a
correct implementation for mptscsih_dev_reset(), and renames the original
function to mptscsih_target_reset().
