[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 Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: Anil Veerabhadrappa <anilgv@broadcom.com> Reviewed-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
