of_partition() calls of_node_get() on the parent device node at the
beginning of the function, storing the reference in 'partitions_np'.
This reference is leaked in two paths:
1. The compatibility check at the top of the function returns 0
without releasing partitions_np when the node exists but is not
"fixed-partitions" compatible.
2. The function returns 1 at the end after successfully processing
all partitions without releasing partitions_np.
Fix both leaks by adding of_node_put(partitions_np) on each path.
Fixes: 2e3a191e89 ("block: add support for partition table defined in OF")
