be2net: Missing byteswap in be_get_fw_log_level causes oops on PowerPC

commit ac46a462 upstream.

We are seeing an oops in be_get_fw_log_level on ppc64 where we walk
off the end of memory.

commit 941a77d5 (be2net: Fix to allow get/set of debug levels in
the firmware.) requires byteswapping of num_modes and num_modules.
