iscsi-target: avoid NULL pointer in iscsi_copy_param_list failure
commit 8ae757d09c45102b347a1bc2867f54ffc1ab8fda upstream.
In iscsi_copy_param_list() a failed iscsi_param_list memory allocation
currently invokes iscsi_release_param_list() to cleanup, and will promptly
trigger a NULL pointer dereference.
Instead, go ahead and return for the first iscsi_copy_param_list()
failure case.
Found by coverity.
