[ Upstream commit 67c3e59443f5fc77be39e2ce0db75fbfa78c7965 ]
The call to of_find_compatible_node() returns a node pointer with
refcount incremented thus it must be explicitly decremented here
before returning.
Fixes: a489043f4626 ("powerpc/pseries: Implement arch_get_random_long() based on H_RANDOM")
