[PATCH 5.9 44/75] dm writecache: fix the maximum number of arguments

[Greg Kroah-Hartman]

From: Mikulas Patocka <mpatocka@xxxxxxxxxx>

commit 67aa3ec3dbc43d6e34401d9b2a40040ff7bb57af upstream.

Advance the maximum number of arguments to 16.
This fixes issue where certain operations, combined with table
configured args, exceed 10 arguments.
