[LTP] [PATCH] preadv203: set max_runtime to 270s

[Li Wang <liwang@redhat.com>]

Before the runtime patchset preadv203 use 5min as default timeout
per fs, that's really long enough for prepare_device(). But after
that, its now only has 30s which might be short for a slower system
to do preparation work.

Let's set max_runtime to 270s to make the timeout at least equal
to previously.

Notes:
    Another fixe way is going with define DEFAULT_TIMEOUT to 60, that
    generally extends all timeout for each fs to perform prepare_device().
    And this will impact all test cases with setting .all_filesystems.
