Fix possible integer overflow.

In pool_write_flush() and pool_flus_it() write(2) is used. write(2)
returns ssize_t and in the code there are some places where the return
value was assigned to an int variable. As a result it was possible
that the return value was evaluated to negative value, which led to an
error.

Backpatch-through: v4.3
