Subject: [PATCH 3.14 35/43] be2iscsi: Fix kernel panic when device initialization fails

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: John Soni Jose <sony.john-n@...lex.com>

commit 2e7cee027b26cbe7e6685a7a14bd2850bfe55d33 upstream.

Kernel panic was happening as iscsi_host_remove() was called on
a host which was not yet added.
