scsi: fcoe: Fix transport not deattached when fcoe_if_init() fails
[ Upstream commit 4155658cee394b22b24c6d64e49247bf26d95b92 ]
fcoe_init() calls fcoe_transport_attach(&fcoe_sw_transport), but when
fcoe_if_init() fails, &fcoe_sw_transport is not detached and leaves freed
&fcoe_sw_transport on fcoe_transports list. This causes panic when
reinserting module.
BUG: unable to handle page fault for address: fffffbfff82e2213
RIP: 0010:fcoe_transport_attach+0xe1/0x230 [libfcoe]
Call Trace:
