LoongArch: KVM: Move some variable declarations to paravirt.h

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

Move these variable declarations to header file asm/paravirt.h to avoid
compiling warnings.

Fixes: c43dce6f13 ("LoongArch: KVM: Make vcpu_is_preempted() as a macro rather than function")
