 plug-ins/dds: fix #12790 for 32-bit

On 32-bit systems the computed linear size can overflow, causing a
crash.
Use a function that checks for overflow when multiplying and return
an error if that fails.
As extra security also update the loop to compute the base offset after
each line of data, and convert to gsize first when computing the
size for g_malloc and memset.

(cherry picked from commit c17b324910204a47828d6fbb542bdcefbd66bcc1)
