Subject: [PATCH, net-next] qede: hide 32-bit compile warning

The addition of the per-queue statistics introduced a harmless warning
on all 32-bit architectures:

drivers/net/ethernet/qlogic/qede/qede_ethtool.c: In function 'qede_get_ethtool_stats':
drivers/net/ethernet/qlogic/qede/qede_ethtool.c:244:31: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
      buf[cnt++] = QEDE_TQSTATS_DATA(edev,
                               ^
drivers/net/ethernet/qlogic/qede/qede_ethtool.c:244:22: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
      buf[cnt++] = QEDE_TQSTATS_DATA(edev,
                      ^
This changes the cast to 'void *' to shut up the warning, which
avoids the assumptions on the size of the pointer type.

Signed-off-by: Arnd Bergmann <arnd@...db.de>
Fixes: 68db9ec2df07 ("qede: Add support for per-queue stats.")
