Some variables relative with paravirt feature are declared in header file
asm/qspinlock.h, however this file can be included only when option
CONFIG_SMP is on. There is compiling warning if CONFIG_SMP is off since
it is not declared.

Move these variable declaration to header file asm/paravirt.h to avoid
compiling warning.
