[PATCH -next] misc/pvpanic: Make some symbols static

[YueHaibing]

Fix sparse warnings:

drivers/misc/pvpanic/pvpanic.c:28:18: warning:
 symbol 'pvpanic_list' was not declared. Should it be static?
drivers/misc/pvpanic/pvpanic.c:29:12: warning:
 symbol 'pvpanic_lock' was not declared. Should it be static?
