The permissions on this debugfs file are 0444 so it can't be written to.
And writing to the file hasn't done anything since commit 6e9548cdb30e
("ASoC: SOF: Convert the generic IPC flood test into SOF client").
Delete the write function.

I haven't tested this patch and there is a risk that it breaks some of
the test scripts. Another option would be to just make it a dummy
function that does { return count; }. But I thought I would try the
better option first.
Please review this extra carefully.
