<div class='commit-subject'>coredump: fix dumping through pipes</div><div class='commit-msg'>The offset in the core file used to be tracked with -&gt;written field of
the coredump_params structure. The field was retired in favour of
file-&gt;f_pos.

However, -&gt;f_pos is not maintained for pipes which leads to breakage.

Restore explicit tracking of the offset in coredump_params. Introduce
-&gt;pos field for this purpose since -&gt;written was already reused.

Fixes: a00839395103 ("get rid of coredump_params-&gt;written").
