vb2: core: Skip planes array verification if pb is NULL
commit 126f40298446a82116e1f92a1aaf72b8c8228fae upstream.
An earlier patch fixing an input validation issue introduced another
issue: vb2_core_dqbuf() is called with pb argument value NULL in some
cases, causing a NULL pointer dereference. Fix this by skipping the
verification as there's nothing to verify.
Fixes: e7e0c3e26587 ("[media] videobuf2-core: Check user space planes array in dqbuf")
