dm bufio: initialize read-only module parameters
commit 4cb57ab4a2e61978f3a9b7d4f53988f30d61c27f upstream.
Some module parameters in dm-bufio are read-only. These parameters
inform the user about memory consumption. They are not supposed to be
changed by the user.
However, despite being read-only, these parameters can be set on
modprobe or insmod command line, for example:
modprobe dm-bufio current_allocated_bytes=12345
The kernel doesn't expect that these variables can be non-zero at module
initialization and if the user sets them, it results in BUG.
This patch initializes the variables in the module init routine, so that
user-supplied values are ignored.
