[PATCH] crypto: cavium/nitrox - Fix format strings

[Arnd Bergmann <arnd@arndb.de>]

The return type of atomic64_read() is unfortunately architecture
specific, it can be 'long', 'long long', or 's64'. When it is 'long',
we get a build warning:

drivers/crypto/cavium/nitrox/nitrox_debugfs.c: In function 'stats_show':
drivers/crypto/cavium/nitrox/nitrox_debugfs.c:62:30: error: format '%lld' expects argument of type 'long long int', but argument 3 has type 'long int' [-Werror=format=]
  seq_printf(s, "  Posted: %lld\n", atomic64_read(&ndev->stats.posted));
                           ~~~^
                           %ld
drivers/crypto/cavium/nitrox/nitrox_debugfs.c:63:33: error: format '%lld' expects argument of type 'long long int', but argument 3 has type 'long int' [-Werror=format=]
  seq_printf(s, "  Completed: %lld\n",
                              ~~~^
                              %ld
drivers/crypto/cavium/nitrox/nitrox_debugfs.c:65:31: error: format '%lld' expects argument of type 'long long int', but argument 3 has type 'long int' [-Werror=format=]

Add an explicit cast to 's64' to get a consistent behavior on all
architectures here during compile testing.
