app/testpmd: fix show RSS RETA on Windows

[ upstream commit 5aae272 ]

Replaced using strtoul with strtoull when converting to
64-bit mask field.
In Windows strtoul returns 32-bit values which cause an
issue with show RSS RETA.

Fixes: 66c5949 ("ethdev: support multiple sizes of redirection table")
