dm stats: initialize read-only module parameter
commit 76f5bee5c3b45c617f91243e85547fc8f67bc678 upstream.
The module parameter stats_current_allocated_bytes in dm-mod is
read-only. This parameter informs the user about memory
consumption. It is not supposed to be changed by the user.
However, despite being read-only, this parameter can be set on
modprobe or insmod command line:
modprobe dm-mod stats_current_allocated_bytes=12345
The kernel doesn't expect that this variable can be non-zero at module
initialization and if the user sets it, it results in warning.
This patch initializes the variable in the module init routine, so
that user-supplied value is ignored.
