drivers/firmware/psci: Fix memory leakage in alloc_init_cpu_groups()
[ Upstream commit c377e67c6271954969384f9be1b1b71de13eba30 ]
The CPU mask (@tmp) should be released on failing to allocate
@cpu_groups or any of its elements. Otherwise, it leads to memory
leakage because the CPU mask variable is dynamically allocated
when CONFIG_CPUMASK_OFFSTACK is enabled.
