Mauricio Vásquez fba60b171a libbpf: Use IS_ERR_OR_NULL() in hashmap__free() 
hashmap__new() uses ERR_PTR() to return an error so it's better to
use IS_ERR_OR_NULL() in order to check the pointer before calling
free(). This will prevent freeing an invalid pointer if somebody calls
hashmap__free() with the result of a failed hashmap__new() call.
