dm ioctl: Fix compilation warning
In retrieve_status(), when copying the target type name in the
target_type string field of struct dm_target_spec, copy at most
DM_MAX_TYPE_NAME - 1 character to avoid the compilation warning:
warning: ‘__builtin_strncpy’ specified bound 16 equals destination
size [-Wstringop-truncation]
when compiling with W-1.
