crypto: ux500 - Remove set but not used variable 'cookie'
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/crypto/ux500/hash/hash_core.c: In function hash_set_dma_transfer:
drivers/crypto/ux500/hash/hash_core.c:143:15: warning: variable cookie set but not used [-Wunused-but-set-variable]
It is not used since commit 8a63b1994c50 ("crypto:
ux500 - Add driver for HASH hardware")
