cpufreq/longhaul: handle NULL policy in longhaul_exit
[ Upstream commit 592532a77b736b5153e0c2e4c74aa50af0a352ab ]
longhaul_exit() was calling cpufreq_cpu_get(0) without checking
for a NULL policy pointer. On some systems, this could lead to a
NULL dereference and a kernel warning or panic.
This patch adds a check using unlikely() and returns early if the
policy is NULL.
