hv: fix error debug message in hcall_set_callback_vector

Browse Source 
this patch is to fix error debug message
 for invalid 'param' case, there is no string
 variable for '%s' output, which will potenially
 trigger hypervisor crash as it may access random
 memroy address and trigger SMAP violation.
