scsi: be2iscsi: Add checks to validate CID alloc/free

[ Upstream commit 413f365657a8b9669bd0ba3628e9fde9ce63604e ]

Set CID slot to 0xffff to indicate empty.
Check if connection already exists in conn_table before binding.
Check if endpoint already NULL before putting back CID.
Break ep->conn link in free_ep to ignore completions after freeing.
