KVM: SVM: Fix benign "bool vs. int" comparison in svm_set_cr0()

Explicitly convert the return from is_paging() to a bool when comparing
against old_paging, which is also a boolean.  is_paging() sneakily uses
kvm_read_cr0_bits() and returns an int, i.e. returns X86_CR0_PG or 0, not
1 or 0.

Luckily, the bug is benign as it only results in a false positive, not a
false negative, i.e. only causes a spurious refresh of CR4 when paging is
enabled in both the old and new.
