test/fio/fio_ceph_messenger: fix str_to_ptr() crash at windows

I compiled a "fio_ceph_messenger. DLL" running on windows for FIO
testing, but the original code is Linux, and the default size of long
is 64 bits, but it is 32 bits on windows, resulting in a crash during
pointer conversion. Now it has been running well in my computer
