Fixes gcc '-Wunused-but-set-variable' warning:

drivers/crypto/chelsio/chcr_algo.c: In function 'chcr_device_init':
drivers/crypto/chelsio/chcr_algo.c:1371:18: warning:
 variable 'adap' set but not used [-Wunused-but-set-variable]

It not used since commit a1c6fd43 ("crypto: chelsio - Update ntx queue
