Fix a loophole in nonrd_pick_partition()

In some rare cases, all possible paritions may be skipped during RD
search. The patch makes the encoder do rectangular partition search if
both partition-none and partition-split are not allowed.

Tested on the rtc and ytlivehr testsets with speed 5 and 7, no coding
stats changes were observed.
