[SCSI] bnx2i: bug fixes in bnx2i_init_one to handle error conditions 

Fixed bnx2i_init_one() to properly handle return code of
cnic->register_device() and propagate it back to the caller.  No need to check
for BNX2I_CNIC_REGISTERED, because unless the adapter is added to adapter_list
it will not be registered in ep_connect context
