scsi: hpsa: fix an uninitialized read and dereference of pointer dev

Browse Source 
Currently the check for a lockup_detected failure exits via the label
return_reset_status that reads and dereferences an uninitialized pointer
dev.  Fix this by ensuring dev is inintialized to null.

Addresses-Coverity: ("Uninitialized pointer read")
Fixes: 14991a5bade5 ("scsi: hpsa: correct device resets")
