bpf: add missing percpu_counter_destroy() in htab_map_alloc()
syzbot is reporting ODEBUG bug in htab_map_alloc() [1], for
commit 86fe28f7692d96d2 ("bpf: Optimize element count in non-preallocated
hash map.") added percpu_counter_init() to htab_map_alloc() but forgot to
add percpu_counter_destroy() to the error path.
