Subject: [PATCH] HID: nintendo: Fix unused-const-variable compiler warning

The following compiler warning is produced when CONFIG_NINTENDO_FF
is not set:

>> drivers/hid/hid-nintendo.c:405:29: warning: 'JC_RUMBLE_ZERO_AMP_PKT_CNT'
   defined but not used [-Wunused-const-variable=]

To fix this, move the variable 'JC_RUMBLE_ZERO_AMP_PKT_CNT' under the
CONFIG_NINTENDO_FF's conditional compilation block.
