crypto: marvell - Remove set but not used variable 'ivsize'

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

drivers/crypto/marvell/cipher.c: In function 'mv_cesa_skcipher_dma_req_init':
drivers/crypto/marvell/cipher.c:325:15: warning:
 variable 'ivsize' set but not used [-Wunused-but-set-variable]

It's not used any more after 0c99620f0ac1 ("crypto: marvell - Use an unique
pool to copy results of requests")
