Don't populate the read-only array descs on the stack but instead it
static and add extra const. Also makes the object code smaller by 66
bytes:
Before:
text data bss dec hex filename
42382 11140 512 54034 d312 ./drivers/md/dm-clone-target.o
After:
text data bss dec hex filename
42220 11236 512 53968 d2d0 ./drivers/md/dm-clone-target.o
(gcc version 11.2.0)
