Subject: [PATCH 2/5] ath10k: Remove unused 'num_vdev_stats' variable

Several functions for wmi stats parsing define and set num_vdev_stats
but do not use it. Compiling with W=1 gives the following warnings,
fix them.

drivers/net/wireless/ath/ath10k/wmi.c: In function ‘ath10k_wmi_main_op_pull_fw_stats’:
drivers/net/wireless/ath/ath10k/wmi.c:2680:22: warning: variable ‘num_vdev_stats’ set but not used [-Wunused-but-set-variable]
  u32 num_pdev_stats, num_vdev_stats, num_peer_stats;
                      ^
drivers/net/wireless/ath/ath10k/wmi.c: In function ‘ath10k_wmi_10x_op_pull_fw_stats’:
drivers/net/wireless/ath/ath10k/wmi.c:2735:22: warning: variable ‘num_vdev_stats’ set but not used [-Wunused-but-set-variable]
  u32 num_pdev_stats, num_vdev_stats, num_peer_stats;
                      ^

  u32 num_vdev_stats;
      ^

These are harmless warnings and are only being fixed to reduce the
noise with W=1 in the kernel.
