USB: serial: mos7840: fix NULL-deref at open
commit 5c75633ef751dd4cd8f443dc35152c1ae563162e upstream.
Fix NULL-pointer dereference in open() should the device lack the
expected endpoints:
Unable to handle kernel NULL pointer dereference at virtual address 00000030
...
PC is at mos7840_open+0x88/0x8dc [mos7840]
Note that we continue to treat the interrupt-in endpoint as optional for
now.
Fixes: 3f5429746d91 ("USB: Moschip 7840 USB-Serial Driver")
