[PATCH] EDAC: remove unnecessary static in edac_fake_inject_write()

["Gustavo A. R. Silva" <garsilva@embeddedor.com>]

Remove unnecessary static on local variable _type_.
Such variable is initialized before being used,
on every execution path throughout the function.
The static has no benefit and, removing it reduces
the code size.

This issue was detected using Coccinelle and the following semantic patch:

@bad exists@
position p;
identifier x;
type T;
@@

static T x@p;
...
x = <+...x...+>

@@
identifier x;
expression e;
type T;
position p != bad.p;
@@

-static
 T x@p;
 ... when != x
     when strict
?x = e;

In the following log you can see the difference in the code size and,
also a significant difference in bss segment. This log is the output
of the size command, before and after the code change:

before:
   text    data     bss     dec     hex filename
   2966     920     128    4014     fae drivers/edac/debugfs.o

after:
   text     data     bss    dec     hex filename
   2961     832      64    3857     f11 drivers/edac/debugfs.o
