net: page_pool: add missing free_percpu when page_pool_init fail
[ Upstream commit 8ffbd1669ed1d58939d6e878dffaa2f60bf961a4 ]
When ptr_ring_init() returns failure in page_pool_init(), free_percpu()
is not called to free pool->recycle_stats, which may cause memory
leak.
Fixes: ad6fa1e1ab1b ("page_pool: Add recycle stats")
