[patch -resend] 9p: fix min_t() casting in p9pdu_vwritef()

[Dan Carpenter]

I don't think we're actually likely to hit this limit but if we do
then the comparison should be done as size_t.  The original code
is equivalent to:
        len = strlen(sptr) % USHRT_MAX;

I was told this patch "has already made it upstream via the v9fs pull."
but it must have been dropped accidentally.  Originally sent on Sat,
