USB: serial: io_edgeport: fix NULL-deref at open
commit 0dd408425eb21ddf26a692b3c8044c9e7d1a7948 upstream.
Fix NULL-pointer dereference when initialising URBs at open should a
non-EPIC device lack a bulk-in or interrupt-in endpoint.
Unable to handle kernel NULL pointer dereference at virtual address 00000028
...
PC is at edge_open+0x24c/0x3e8 [io_edgeport]
Note that the EPIC-device probe path has the required sanity checks so
this makes those checks partially redundant.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
