crypto: nx842 - remove set but not used variables 'dpadding' and 'max_sync_size'

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

drivers/crypto/nx/nx-842.c: In function 'decompress':
drivers/crypto/nx/nx-842.c:356:25: warning: variable 'dpadding' set but not used [-Wunused-but-set-variable]
drivers/crypto/nx/nx-842-pseries.c: In function 'nx842_pseries_compress':
drivers/crypto/nx/nx-842-pseries.c:299:15: warning: variable 'max_sync_size' set but not used [-Wunused-but-set-variable]
drivers/crypto/nx/nx-842-pseries.c: In function 'nx842_pseries_decompress':
drivers/crypto/nx/nx-842-pseries.c:430:15: warning: variable 'max_sync_size' set but not used [-Wunused-but-set-variable]

They are not used any more and can be removed.
