fio.h: also check trim operations in fio_ro_check

IO engines call fio_ro_check to ensure that the data direction
set in the thread data structure permits writes before proceeding
with a write io_u. This patch makes fio_ro_check ensure that the
data direction also permits trims before proceeding with a trim
io_u.
