Mikulas Patocka 86f4a49f32 dm: limit the number of targets and parameter size area
commit bd504bcfec upstream.

The kvmalloc function fails with a warning if the size is larger than
INT_MAX. The warning was triggered by a syscall testing robot.

In order to avoid the warning, this commit limits the number of targets to
1048576 and the size of the parameter area to 1073741824.
