mtd: maps: Eliminate use after free

Moved the debugging message before the call to map_destroy, which frees its
argument.  The message is also slightly changed to reflect its new
position.

A simplified version of the semantic patch that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression E,E2;
@@

del_mtd_device(E)
...
(
  E = E2
|
* E
)
// </smpl>
