crypto: fix broken crypto_register_instance() module handling
Commit 8e239e586ec3 ("crypto: api - remove instance when test failed")
tried to grab a module reference count before the module was even set.
Worse, it then goes on to free the module reference count after it is
set so you quickly end up with a negative module reference count which
prevents people from using any instances belonging to that module.
This patch moves the module initialisation before the reference
count.
