util/nvmutil: move looping logic to rw_file_exact

rw_file_once was doing what rw_file_exact should be
doing

_once does what it says: once

we were passing an offset (rc) to it that it was not
meaningfully using.

this makes the code now more robust, especially if
we later swap out or break _once - then we don't
get weird behaviour (if there is a regression).
