Drivers: hv: Fix the check for HYPERVISOR_CALLBACK_VECTOR

Browse Source 
__is_defined(HYPERVISOR_CALLBACK_VECTOR) would return 1, only if
HYPERVISOR_CALLBACK_VECTOR macro is defined as 1. However its value is
0xf3 and this leads to __is_defined() returning 0. The expectation
was to just check whether this MACRO is defined or not and get 1 if
it's defined. Replace __is_defined with #ifdef blocks instead to
fix it.
