[PATCH] crypto: img-hash: remove unnecessary static in img_hash_remove()

Remove unnecessary static on local variable hdev. 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 significant 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
  14842    6464     128   21434    53ba drivers/crypto/img-hash.o

after:
   text    data     bss     dec     hex filename
  14789    6376      64   21229    52ed drivers/crypto/img-hash.o
