crypto: omap-sham - remove unnecessary static in omap_sham_remove()

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

This issue was detected using Coccinelle and the following semantic patch:
https://github.com/GustavoARSilva/coccinelle/blob/master/static/static_unused.cocci

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

before:
   text    data     bss     dec     hex filename
  26135   11944     128   38207    953f drivers/crypto/omap-sham.o

after:
   text    data     bss     dec     hex filename
