crypto: tcrypt - fix ghash-generic speed test

Browse source 
commit 331351f89c36bf7d03561a28b6f64fa10a9f6f3a upstream.

ghash is a keyed hash algorithm, thus setkey needs to be called.
Otherwise the following error occurs:
$ modprobe tcrypt mode=318 sec=1
testing speed of async ghash-generic (ghash-generic)
tcrypt: test  0 (   16 byte blocks,   16 bytes per update,   1 updates):
tcrypt: hashing failed ret=-126
