Subject: [PATCH] scsi: bnx2i: missing error code in bnx2i_ep_connect()

commit 1d32a62c74b3bcb69822b0f4745af5410cfec3a7 upstream.

If bnx2i_map_ep_dbell_regs() then we accidentally return NULL instead of
an error pointer.  It results in a NULL dereference in
iscsi_if_ep_connect().

Fixes: cf4e6363859d ("[SCSI] bnx2i: Add bnx2i iSCSI driver.")
