Subject: [PATCH] crypto: tcrypt - fix ghash-generic speed test

References: bsc#1051510
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
