Use only preallocated memory in ngx_readv_chain() (ticket #1408).
In d1bde5c3c5d2, the number of preallocated iovec's for ngx_readv_chain()
was increased. Still, in some setups, the function might allocate memory
for iovec's from a connection pool, which is only freed when closing the
connection.
The ngx_readv_chain() function was modified to use only preallocated
memory, similarly to the ngx_writev_chain() change in 8e903522c17a.
