[v2,1/5] fsdev/9p-iov-marshal.c: Don't use cpu_to_*w() functions

Commit Message

Peter Maydell July 7, 2016, 4:20 p.m. UTC

Don't use the cpu_to_*w() functions, which we are trying to deprecate.
Instead just use cpu_to_*() to do the byteswap, which brings the
code in the marshal function in line with that in the unmarshal.
