x86/hyperv: Fix smp_ops build failure on UP kernels
CI testing found this build failure:
arch/x86/hyperv/hv_crash.c:631:9: error: ‘smp_ops’ undeclared (first use in this function)
And I bisected it back to the initial commit that enabled this feature:
77c860d2dbb72d1f3c6a2e882a07d19eca399db5 is the first bad commit
commit 77c860d2dbb72d1f3c6a2e882a07d19eca399db5 (HEAD)

x86/hyperv: Enable build of hypervisor crashdump collection files
Hyperv should probably be limited to SMP kernels, as nobody
appears to be testing it on UP kernels.
Until then, fix the smp_ops assumption. Build tested only.
