Fixed division by zero exception in ngx_hash_init().
The ngx_hash_init() function did not expect call with zero elements count,
which caused FPE error on configs with an empty "types" block in http context
and "types_hash_max_size" > 10000.
Example configuration to reproduce:
events { }
http {
types_hash_max_size 10001;
types {}
server {}
}
